Alec Baldwin and his new wife Hilaria Thomas are rumoured to be expecting a baby.

The 30 Rock star and the 28-year-old yoga teacher - who tied the knot in New York last summer - are said to be thrilled about the news.

A source told InTouch Weekly: "Hilaria has told only really close friends and family she is pregnant, only a close circle she trusts."

Alec, 54, who has a 17-year-old daughter, Ireland, from his former marriage to actress Kim Basinger, hasn't confirmed or denied the rumours he is set to become a dad again.

But his publicist Matthew Hiltzik said on the firm's Twitter page: "Part 1 -re: @abfalecbaldwin / @hilariabaldwin: Our response to baby speculation over the past 18 months has remained the same..."

He went on: "pt2: re:@abfalecbaldwin/@hilariabaldwin. when/if Alec&Hilaria have news they want 2 share, they will share it. Until then, no comment."
