Minnie Driver has been doing her crunches.
The About a Boy star is vacationing in Miami with her 5-year-old son, Henry, and some family friends who also have kids, but this afternoon she was alone and showing off her toned legs and impressive abs in a green floral-print, ruffle-trimmed bikini while walking on the beach.
Driver capped off her look with the requisite brimmed hat and sunglasses to protect her face from the sun.
A source exclusively tells E! News that the 44-year-old actress headed from her nearby hotel to the shore at around 4 p.m., local time, for her stroll.
She amiably obliged the waiting paparazzi with a 10-minute loop up and down the beach, enough for them to get plenty of shots while she was not busy having family time with her kid.
Eyewitnesses said that earlier in the day, when Henry was with her, Driver also seemed to be in a really good mood, laughing and looking very happy.
Driver, best known for Circle of Friends and Good Will Hunting and the FX dramedy The Riches, now stars in the NBC adaptation of the 2002 comedy About a Boy, taking on the role of the quirky mum played by Toni Collette in the movie.
