Looking good, Hilary Duff!
The 25-year-old hot mama showed off her bikini body while celebrating Mother's Day with son Luca, husband Mike Comrie and other family over the weekend.
The happy fam, who are on vacation in Cabo San Lucas, Mexico, celebrated the holiday by soaking up the sun by the pool and taking in the beach scenery.
Duff, dressed in a dark green two-piece bikini with a white scarf wrapped around her head, was snapped holding her 1-year-old son. Duff's sister Haylie was also seen taking little Luca for a stroll on the beach after lunch.
"Feel so very lucky to be a mother today!" she tweeted on Sunday. "And everyday! Happy mothersday 2all the mothers out there,it can b a hard job but the best! Good work!"
