Kate Hudson's growing bump is ready to hit the beach!

The pregnant actress, 31, proudly showed off her belly in a skimpy two-piece in Mexico on March 6.


Vacationing with son Ryder, 7, and beau-turned-baby daddy Matthew Bellamy, the actress soaked up the Cabo sun, accenting her bikini with a Theodora & Callum Paisley Eye Scarf.


"They are really happy," a source tells Us of the couple, who started dating after meeting backstage at the Coachella music festival in Indio, California last April. See more photos of Kate's bare baby belly.


Still, the Something Borrowed star, due this summer, isn't quite ready to wed the Brit rocker, 32. Her focus? Prepping for baby No. 2. "Kate is happy for Ryder to finally have a brother or sister," says a friend. Adds another insider, "she's a great mom."
