Wilmer Valderrama Surprised By 35th Birthday Bash Thrown By Girlfriend Demi Lovato

How cool a girlfriend is Demi Lovato? She threw a big celebration for boyfriend actor Wilmer Valderrama‘s 35th birthday!

The 22-year-old singer put together the party at Palms Thai in Los Angeles on Thursday night (January 29) and it was packed full of Wilmer‘s closest friends and family, a source told US Weekly.

“They were definitely celebrating and enjoying themselves,” the source shared. “Wilmer got there later, giving his friends a chance to get there first. He was surprised!”

They added, “[Wilmer's That 70s Show co-stars and new parents] Mila [Kunis] and Ashton [Kutcher] seemed to be having a great time. Demi and Wilmer were really cute together too.”

The group dined on pad thai noodles, barbecue chicken, soup and sipped on an array of cocktails before presenting Wilmer with a W shaped cake and sang “For He’s a Jolly Good Fellow.”

Wilmer posted up on Instagram with the cake, “IT’S MY BIRTHDAY!!!! Haha!! I was surprised last night by all the people I love!! I felt so blessed to have looked around & truly know that everyone by my side has & will always have my back. I love you! 35, does that mean is cheaper when I go to Disneyland!?”

Demi added later on, “Here’s to many more incredible years together. Happy Birthday my love…. I love you.”
