Yes, she's FOURTYFIVE. Here's Halle celebrating herself in a bikini, while frolicking about Malibu Beach (where all the enviable bodies evidently convene) on Sunday.

She enjoyed getting her arse out in the company of her boyfriend Olivier 'I also used to do Kylie Minogue' Martinez (seen here in the blue shirt), her daughter, and some friends - all of which remained fully clothed for some reason... even when they set about roughly tackling her into the sea before happily molesting her among the rocks. Which is a most comfortable activity to undertake in damp jeans - so we're not sure who the joke's on exactly.  Her female companion seemed pleased to administer the more familiar interpretation of 'the bumps' regardless.
