It’s not just women being cougars anymore.

Yesterday, we told you that 57-year old Bruce Willis and his 33-year old wife Emma Hemming just welcomed a baby girl, Mable Ray Willis. And now another celeb man-coug is in the news for making it official with his much younger girlfriend.

Alec Baldwin, who just turned 54 today, popped the question to his 28-year old yoga instructor girlfriend. He’s been dating Hilaria Thomas for about a year and he asked her to marry him over the weekend. She was spotted in New York yesterday flashing her new diamond ring. Alec said he is considering having children with her. He already has a 16 year old ‘thoughtless little pig’ daughter, Ireland, with his ex-wife Kim Bassinger.
