She showed up in a bra and panties in Tootsie and had a one night stand with Brad Pitt in Thelma and Louise.

But what has Geena Davis been up to lately?

Mommy-hood! A fuller-figured -- but still beaming! -- Davis showed up in a Santa Monica, Calif. park Tuesday as her three kids frolicked on the swings.

After her ABC show Commander in Chief (she played a female president) was cancelled after one season in 2006, the Oscar-winning actress seems to have kept her acting work to a minimum.

Instead, the 53 year-old has devoted much of her time to daughter Alizeh, 7, and fraternal sons Kian and Kaiis; the father of her late-in-life kids is Davis' husband of 9 years, plastic surgeon Reza Jarrahy.

Davis -- also a former model, an Olympic archery semifinalist (in 1999) and a high-IQ member of MENSA -- is scheduled to speak in Detroit, Mich. on Nov. 18 on behalf of the White House Project, a nonprofit aimed at promoting women in political positions.
