Gogo Mastrokosta passed away at 56 after a long battle with cancer.

In recent months, she had been hospitalized at Evangelismos Hospital, with her family by her side as she fought her final battle for life — one she sadly could not win.

Her daughter announced her death shortly after 1 a.m.

Born in 1970 in Evinochori, Aetolia-Acarnania, Gogo Mastrokosta took a long time to realize how much future generations would talk about her name and image. She never imagined it.

“My mother never told me I was beautiful. She finally said it when I was 30. I had no self-confidence at all. I would pass by a mirror and say, ‘Ugh, go away.’”

Grounded in a different reality, she never pursued the kind of career usually chosen by women competing for the title of beauty queen or sex symbol.

She followed the path of education, studying at the Academy of Physical Education, and it was her role as a fitness instructor that eventually opened the doors to show business. Her television career began in 1995 on the Mega TV show Metaxy Mas (“Between Us”), where she hosted a fitness segment — a staple of highly rated morning programs at the time. More television appearances followed, and she soon became Greece’s “national TV fitness instructor.”

She herself remained relatively indifferent to the fame and also tried her hand at singing. In 2007, she released her own album titled Amartia (“Sin”).

Her photos created a sensation, magazines discovered a new cover star, and her presence inspired admiration. During the 2000s, Gogo Mastrokosta became the ultimate sex symbol for several years — and it was then that she met the great love of her life: Traianos Dellas.

Gogo Mastrokosta and Traianos Dellas met through a mutual acquaintance at a nightclub, where their first interaction sparked a love story that would grow deeply over time.
“I didn’t fall in love with him immediately. He was intimidating when I first saw him. Very masculine. I saw this two-meter-tall man and thought he was a bit too much for me. I met him ten months after his divorce. Let’s make that clear, because I’ve heard people say I was the reason for his separation!”

She described their relationship as far from ideal in the beginning, but something that felt destined.
“From the very first moment, I knew I wanted children with Traianos. But I didn’t know if it would happen, because I met my husband at a very strange phase in his life. After a breakup, when a man becomes single again, he wants to enjoy his freedom for a while. That’s exactly the phase I met him in. I had to be patient. After a year, we finally said we were in a relationship.

For me, we were together from the first minute. For Traianos, it took a year. But I appreciated his honesty and knew that when this man said he was with me, he truly would be. During the first year, I felt like I was part of a ‘harem.’ It gave me anxiety, but I liked him so much, and thankfully I looked beyond it. At the start of our relationship, I lived in his house and he still wouldn’t give me keys.”

Their second meeting took place in Kolonaki, where he asked her out and she accepted. The couple managed to keep their relationship away from the public eye for some time, though it became publicly known in January 2007 after they appeared together at a club.

Later, Traianos asked her to move in with him. Soon after, she became pregnant, and on December 9, 2008, they welcomed their daughter, Viktoria.

“The marriage proposal took a while. I was already four or five months pregnant and still no proposal. So in the sixth month I told Traianos, ‘We’ll baptize our daughter Viktoria Mastrokosta.’ Viktoria is his mother’s name, and Mastrokosta because if you’re not married, the child initially takes the mother’s surname until officially recognized by the father. A few days later, we were at a hotel and he showed me a ring — just like that.”

Three days after their daughter was born, Gogo Mastrokosta was diagnosed with breast cancer.

She first spoke publicly about her battle in 2010. According to her, she realized something was wrong while breastfeeding and experiencing chest pain.

“One thing that hurts me deeply is that I didn’t enjoy the first moments with my child. That part of my life was lost. Childbirth and cancer happened at the same time. And you can’t focus on motherhood because you need all your strength to survive the ordeal that begins. Maybe that was the price for my daughter to come into the world. Even without hair, even when I wasn’t well, Traianos saw me as a goddess. I wish every woman had a partner like mine.”

“Three days after giving birth, my doctor told me I had breast cancer. Before my pregnancy, I had already felt something unusual. You should never rely on just one diagnosis or one doctor. I went to a doctor who didn’t even order a mammogram. I had tests done and was told everything was fine. Then came the moment when they told me. Even before anyone explained anything, I understood. They took me straight into surgery, and when I woke up, the first thing I heard was, ‘Unfortunately, things are not good.’”

“I had to stay isolated and only look at my baby. The fact that I didn’t lose my mind — I’m very lucky. What I could never process was the timing.”

“I was trying to keep my balance. I didn’t get to experience my baby as a baby. I became obsessed with wanting another child. I would hold my baby in my arms, cry, and wonder if I would live to see her grow up.”

The decision to speak publicly about her illness and her fight was one she made together with her husband.

“Traianos told me I should speak openly about breast cancer to help other women. During the first month, I couldn’t handle my illness emotionally. Cancer made me lose my carefree spirit forever.”

Together, they traveled to Chicago to seek treatment at one of America’s most renowned clinics. Speaking later about the experience, she said:

“I find it difficult to talk about it, not for any specific reason, but because I’m not someone who wallows in self-pity. I hate being pitied. But I feel your show gives me a platform to give strength to women, because after all these years I finally feel strong myself. I want to say that things can be overcome.”

The couple remained strong and united throughout her health struggles. Gogo won the first battle. Traianos never left her side.

Although things initially seemed to improve, the cancer returned — this time more aggressively. Still, she did not give up. She fought on and continued treatment.

In October 2024, Traianos Dellas resigned as head coach of OFI Crete in order to stay close to his family.
“After much thought and in complete understanding with the administration, I decided to leave the team due to a very serious personal issue.”

The couple stopped making public appearances, and everyone respected the difficult situation they were going through. In recent days, the sudden deterioration of her health had caused great concern.

In the end, Gogo Mastrokosta lost her battle for life, as her body no longer responded the way doctors had hoped.
