It's been a week of royal baby announcements – first with Kate Middleton's pregnancy, and now with the news (confirmed by E! News) that rock royalty Liv Tyler is expecting, too. 

The 37-year-old Lord of the Rings actress (and our girl crush ever since Aerosmith's Crazy music video) already has a 9-year-old son, Milo William Langdon, from her marriage to British musician Royston Langdon, which ended in 2009. 

And while the father of Liv's second child hasn't been officially announced, she's just gotten back from a romantic holiday with new boyfriend Dave Gardner, who she's been dating for the past few months. Apparently, Liv was introduced to Dave by a mutual friend – Kate Moss, no less. The 40-year-old Brit is a football agent, and longtime friend of David Beckham.

Just imagine the birthday parties - Aerosmith rocker Steven Tyler and playboy model Bebe Buell as grandparents, and Becks and Mossy lighting the candles…
