Ashley Tisdale, known for her role as the snobby Sharpay in the High School Musical films, made her three-decade mark last Thursday. She celebrated her big day at a private dinner at the JustFab House in Malibu where Hyland and Sherwood joined in.

According to Monday's report from People, the couple hung out with Tisdale while also making time for themselves- and this apparently included the Shadowhunters actor teaching his girlfriend proper self-defense moves.

"He was whispering in her ear the whole time," a source said. "He was teaching her defense moves, putting her in a choke lock but teaching her how to get out of it."

Tisdale seemed to have herself a great party that consisted of about 40 people.

"Ashley had each guest stand up and say how they knew her," the source revealed. "The last speech of the night came from her husband, Christopher, who told the crowd how happy he is to be married to Ashley."

Things are apparently going pretty swimmingly for Hyland and Sherwood based on a photo that the Modern Family actress added on Instagram over 4th of July weekend. In the shot, she and her boyfriend take a dip in the pool and get close with each other in a charming embrace.
