Joe Manganiello Celebrates Girlfriend Caitlin O'Connor's 35th Birthday with Sweet Tribute

Joe Manganiello is making sure his girlfriend Caitlin O'Connor is feeling the love on her birthday!

On Aug. 3, the Magic Mike star, 47, shared a sweet Instagram tribute to O’Connor in honor of her 35th birthday alongside several photos of her smiling with him and his beloved pup, Bubbles.

“HAPPY BIRTHDAY CAITLIN!!! ❤️🖤❤️🖤❤️” Manganiello shared. “The World Tour continues… #bussin”

The post comes after the couple had a pre-birthday celebration with her closest friends at upscale Mexican restaurant Toca Madera in West Hollywood on July 14.

"Caitlin had a wonderful time,” a source told PEOPLE last month.

At the time, the insider revealed the pair planned to “enjoy a private celebration by themselves” on her actual birthday.

A source previously told PEOPLE that the pair — who began dating around 11 months ago — "are still going strong” and that Manganiello “treats her like a queen."

"They love spending all of their time together," added the source.

In July 2023, Manganiello filed for divorce from Modern Family star Sofía Vergara, and he began seeing O'Connor in September after the two met through a mutual friend.

In recent months, the couple also took part in "a world tour of sorts," said the source, as they visited Italy, Finland – to see Metallica – and even enjoyed a "very romantic trip" to Paris.

"The Eiffel Tower was right outside their hotel room window. While in France they went to the Louvre, Versailles, the French Open and to see the band Tool," the insider added.

O'Connor also joined Manganiello as he filmed Deal or No Deal Island in Panama and was by his side for a One Tree Hill reunion in North Carolina in May.
