Jaime Pressly and entertainment lawyer Simran Singh are engaged, her rep confirms to PEOPLE. No wedding date has been set.
The pair checked into San Diego's Hard Rock Hotel on Thursday for a celebration toasting the actress's 32nd birthday Friday night, a day after her actual birthday.
Earlier this month she hit the Hollywood hotspot Jane's House to help Pussycat Doll singer Nicole Scherzinger toast her birthday – and let friends in on their big news.
"Jaime was showing off a huge diamond engagement ring on her left hand," says a guest. "Girlfriends were coming up to her and they were all congratulating her on the engagement."
The star of My Name Is Earl
and her man "were an adorable couple. They snuggled in a booth and Jaime even semi-laid down and had her head on his chest," says the guest.
Pressly was previously engaged to Eric Cubiche, from whom she separated
in November of last year. Cubiche is the father of their 2-year-old old son
Dezi James. "We're going through a rough patch," Pressly told Shape
magazine in March. "There are no bad feelings there."
