Sienna Miller: Pregnant With First Child?

Sienna Miller is reportedly expecting a child with beau Tom Sturridge!

The 30-year-old actress and Tom, 26, who’ve been dating for a year, “don’t have plans right away to marry, if at all,” a source tells Us Weekly.

“Friends are really happy with her relationship with Tom,” the source adds. “He’s younger, yes, but he’s mature and he’s a good guy.”

The couple spent the holidays in Paris after telling a group of friends and family that Sienna is pregnant.

Pals weren’t “surprised by the news of the pregnancy,” according to the source. “They’re really good together.”

Congrats to Sienna and Tom – if the happy news is true!!!
