Dressing up a pocketed gray gown with sparkly detailing and simple jewelry, Rachel Griffiths still kept her growing belly under wraps at the Vanity Fair Oscar Party, held Sunday at the Sunset Tower Hotel in West Hollywood, Calif.

Due in July with her third child, Rachel, 40, says her pregnancy won’t be written into Brothers and Sisters as filming is just about completed for the season.

Instead, she and husband Andrew Taylor are concentrating on choosing baby names — one for each sex, as they’re expecting a delivery surprise. “It’s tough now. I’m less oriented to finding an Australian eccentric name I should say. I actually do love the name America,” says the mum to Adelaide Rose, 3 ½ and Banjo Patrick, 5.
