Joe Manganiello‘s birthday cake tasted terribly familiar this year…his girlfriend, Caitlin O’ConnorHe bought his sweet treats from a bakery that his ex-wife often visited. Sofia Vergara.

Bakery sources tell TMZ … Caitlin ordered two birthday cakes for Joe’s birthday from Cake and Art Bakery in West Hollywood, Calif., ahead of his 48th name day … which certainly caused a stir given Sofía’s history with the hotspot.

We’re told the cakes – which cost a whopping $400 in total – each had their own design and flavor. The first dessert was an edible 3D Steelers helmet made from chocolate cake with mocha filling.

The second cake, made of funfetti vanilla with lemon filling, was shaped like a jersey and had the name “Manganiello” engraved on the back.

For those who may not know, Joe is famously from Pittsburgh… so the Steelers theme was a perfect fit for the True Blood alum’s big day. Joe was obviously a fan of the treats as they were later featured on Instagram.

However, Caitlin’s sweet gesture seemed to be a page straight from Sofía’s playbook… because it’s no secret that the “Modern Family” star is a frequent owner of the bakery.

Sources tell us that Caitlin has definitely seen a photo of Joe’s ex with their son. Manolo Gonzalez Vergara, in the bakery… as you know, it’s right at the front and center of the store. There is no way to miss it!!!

However, we are told that the staff did not make the situation embarrassing and chose not to denounce the complex situation.

Sources say Caitlin handled the whole thing well too… Not only was she polite to the staff, but she also had a big smile on her face when she picked up the custom order. Apparently she was just happy to make her husband happy on his birthday…as they say, the way to a man’s heart is through his stomach!!!

Joe and Caitlin announced their relationship in December 2023… months after the actor and his ex-wife announced their separation and plans to divorce.

Since then, Joe and Caitlin have been inseparable…they even recently vacationed in St. Vincent and the Grenadines with JM’s dog.
