Divorce? What divorce? Brazilian fashion model Gisele Bündchen and her embattled husband, New England Patriots quarterback Tom Brady, ignored rumors their marriage was ending. Instead of feeding into the gossip about the status of her relationship, the Brazilian beauty wished her youngest sister, nicknamed “Fafitcha,” a happy birthday on Instagram Friday.

“Happy birthday my little sweetheart! I'm thankful every day for having you in my life,” Bündchen wrote about her sibling. “You are a ray of sunshine in our lives. I wish I could have you by my side all the time, but I know I need to share you with our sisters. I love you so much Fafitcha!”

The bilingual star wrote the post in Portuguese and English. The image received more than 110,000 likes from her 5.9 million followers. If Bündchen looks a little different in the picture, it’s because it’s a throwback. The photo was taken in 1999.

The post comes days after OK! magazine claimed the model and Brady are going through a $460 million divorce. "Things between Tom and Gisele have been strained for a long time,” an insider told the magazine Wednesday.

"We're hearing that they're bickering non-stop lately. And really the drama kind of reached a head at Tom's birthday dinner. Allegedly, Gisele stormed out she was so angry,” Wonderwall’s Jessica Wedemeyer told Entertainment Tonight Thursday.

Even though there are rumors about how much the couple has apparently fought, Bündchen, 35, wished Brady, 38, a happy birthday earlier in the week. However, the online affection may be just for show. “Gisele is ramping up the social media activity because her marriage is breaking down,” an insider told OK! magazine.

If the divorce gossip were true, Bündchen and Brady would not be alone. Reality stars Kourtney Kardashian and Scott Disick recently split after three kids and nearly a decade together; Khloe Kardashian and Lamar Odom finally signed their divorce papers; and the king and queen of country music, Miranda Lambert and Blake Shelton, ended their fairytale marriage this year. Ben Affleck and Jennifer Garner and Gwen Stefani and Gavin Rossdale also filed for divorce in 2015.
