Carmen Electra did an impromptu bikini photo shoot while babysitting her friend's kids yesterday in L.A. -- where the 40-year-old showed off her incredible bod!
Electra, who turned the big 4-0 last month, flaunted her toned tummy and impressive legs in a sexy baby blue two-piece ... which she paired with Louboutin heels, naturally.
Did your babysitter ever look like this?
