The mother of three reveals that there’s a “different energy” around the house since she and husbandCash Warrenwelcomed their third child and first son on Dec. 31.

“Cash just likes that there’s alittle more testosterone in the house,” Alba says, laughing. ” ‘Cause he’s been the only guy for so long.”

The star says her daughters “haven’t changed diapers yet” but are “great” at their big-sister roles. “They help me bathehim in the morning— Haven, my middle one, goes straight into his room and plays with him and cuddles him. They like to give him bottles at night and sing him songs.”

Alba says that despite his gratitude over having another male in the house, her husband isn’t afraid to get his hands dirty(or rather, painted) with his girls.

“He wants to watch sports on the weekends, so he’s like, ‘You can paint my nails if we watch sports,’ ” she shares of Warren, 39. “He doesn’t have to do anything!”
