Sexy starlet Sienna Miller first impressed us with her role in Matthew Vaughn’s raucous crime thriller ‘Layer Cake.’ She teamed with Vaughn again for the fantasy epic ‘Stardust’ and later made us care about ‘G.I. Joe’ all over again as the villainous Baroness in ‘G.I. Joe: The Rise of Cobra.’

The blonde English actress and model’s personal exploits have been well-documented in the tabloid arena – she broke up with Jude Law after he admitted to cheating, she reportedly had an affair with a married actor – but it looks like her personal life has finally settled down a bit.

Miller and fiancé Tom Sturdges are reportedly celebrating the birth of their first child this week.

The addition to the family won’t likely halt Miller’s career for long. She’s always working, which means we can look forward to seeing her long legs and bright eyes in several upcoming projects, including the Nick Cassavettes drama ‘Yellow’ and ‘The Girl,’ loosely based on Alfred Hitchcock’s relationship with actress Tippi Hedren.
