Jennie Garth made sure Monday night was relaxing for herself and for her three kids.
The actress and daughters Luca, Lola and Fiona came through 104.3 My FM’s My Big Night Out 2 VIP lounge, at the Hollywood Bowl, where she was treated to a paraffin massage from a Burke Williams masseuse.
“Jennie told her kids to take photos with her,” an onlooker tells PEOPLE. “She looked amazing and appeared to have shed some pounds. She seemed like she was in a great mood.”
The pop star performed a slew of hits, including, “My Life Would Suck Without You,” “Since U Been Gone” and “Stronger,” along with a cover of Fun.’s “We Are Young.”
Just a couple of days earlier, the Bowl brought out Jerry O’Connell and Eric Stonestreet, who came to watch a performance of The Producers. The musical stars O’Connell’s wife Rebecca Romijn, and Stonestreet’s on-screen Modern Family beau, Jesse Tyler Ferguson.
“Jerry and Eric both looked beaming and happy,” an onlooker tells PEOPLE. “Mel Brooks took the stage at the end.”
