Jennifer Garner sure knows how to keep us guessing.
The hot mother of two hit the Pink Party on Saturday at Drai's wearing a loose pink blouse that conveniently hid her stomach.
She also skipped interviews with all of the media outlets, even though she was the host of the charity soiree. Could it be that she doesn't want to answer any questions about whether she's expecting a third child with hubby Ben Affleck?
Dunno, but inside the party she wasn't spotted sipping any cocktails or bubbly either...
"She was seated at a cabana where you couldn't really see inside," one partygoer tells me. "But when she was on stage and walking around, she wasn't drinking anything."
Also partying for a good cause were Nikki Reed, Denise Richards and Julie Benz. The Pink Party raises money for the Cedars-Sinai Women's Cancer Research Institute.
After getting glammed up Saturday night, Jen was back in her mom jeans on Sunday, when she was spotted toting daugther Seraphina to the park for a playdate.
Blogs were buzzing back in June that Jen had a baby on board, but her camp denied the rumors at the time. Her rep didn't respond to our latest request for comment. (Or maybe we should just try asking Victor Garber?)
So will her girls have a new sibling soon? Stay tuned!
