(Cover) - EN Showbiz - Sienna Miller is enjoying an "adorable" relationship with her partner.

The British actress and her beau Tom Sturridge are currently expecting their first child. Sources close to the couple say they are closer than ever ahead of their new arrival.

"It's quite adorable the way they are together. This baby is going to be so loved," an insider gushed to British magazine Closer.

"They're so happy and it shows in Sienna's appearance. She's so comfortable with Tom and feels she can really be herself with him.

"She's been finding it hard to get glammed up while pregnant. Some days she's so exhausted she hasn't got the effort to dress up and do her hair. But Tom tells her she looks beautiful whatever she's wearing."

Sienna and Tom recently jetted off on a romantic "babymoon" break to Italy. Sources say the trip was just what the pregnant star needed.

"The babymoon has been planned for months. Sienna wanted to completely wind down before the birth, eat good food and go somewhere so chilled she didn't have to feel like she needed to dress up and make an effort," the source continued. (C) Cover Media
