When it comes to Alyson Hannigan's just-spouted spawn, it's already like mother, like daughter. The How I Met Your Mother star and hubby Alexis Denisof welcomed baby girl Satyana Denisof in Los Angeles March 24—which means, for those not already intimately familiar with the signs and stats of the stars, that Hannigan and her mini-me share a birthday.

The camera-ready couple tied the knot back in 2003 in Palm Springs
