It's the battle of the 42-year-old bikini bodies!

Gwen Stefani and Minnie Driver flaunted their hot bodies while on vacation.

Gwen was in Mexico with husband Gavin Rossdale and their two adorable sons Kingston and Zuma. The fair-skinned singer still has the flat stomach she had in her No Doubt days.

Meanwhile, Minnie was in the Caribbean with Matthew Felker. The British actress and the male model, who is eleven years her junior, sported matching six packs.

Both Gwen and Minnie's bodies put women half their age to shame, but whose do you prefer? Check out the photos and vote in our polls below.
