Alec Baldwin fans used to the actors brash antics and Twitter tirades are in for a shock when they see him in the most supportive role may have ever played doting husband and dad-to-be.

Baldwin revealed his softer side in his wife Hilarias new yoga DVD, Fit Mommy-to-Be Prenatal Yoga. The instructional video stars the then-pregnant Mrs. Baldwin coaching her 55-year-old husband to support her in her yoga practice.

The 29-year-old new mother opened up about the couples balance of power in an interview with Vanity Fair.

He very much did what I wanted him to do, she said of the video shoot. I was the boss that day. Were both very bossy people, and that day he let me be the boss.

The couple welcomed a baby girl, Carmen Gabriela, in August.

Baldwin has credited his yogi wifes influence with helping him get happier and healthier.

I think hes wildly in love with his wife, said Howard Bragman, a longtime publicist and ABC News consultant. She has a new project and hes there to support her as any loving husband would do. I think shes been a really good, calming influence on her.
