Baby No. 2! Liv Tyler is pregnant and expecting her second child, sources confirm to Us Weekly. The Leftovers actress, 37, is already a proud mom to 9-year-old son Milo William Langdon, whom she shares with ex-husband Royston Langdon.

UPDATE: Tyler's rep confirms to Us Weekly that she's pregnant.

The mom-to-be, who is currently dating David Beckham's BFF Dave Gardner, was snapped sporting a tiny bump in a bikini while on vacation in Formentera, Spain last month with her beau.

A source tells Us that good friend Kate Moss was the one who introduced Tyler and Gardner. "Dave's perfect for her," the insider adds.

On Tuesday, Sept. 9, the expecting star dined with costar Justin Theroux and Beckham at Il Buco in New York City. Wearing a long cream coat, the actress concealed her baby bump while leaving the restaurant.

Tyler's beau Gardner has two children of his own with ex-wife Davinia Taylor.
