Hilary Duff Hits Recording Studio 7 Months Pregnant!

Hilary Duff has a baby on board and now perhaps a new album, too?

The very pregnant singer/actress, who was all smiles while leaving Pilates class on Friday in Toluca Lake, Calif., seems to have been inspired by her soon-to-be motherhood status and hit up the recording studio the day before.

Back in October, Duff explained to E! News what's in store for her career. "Before I got pregnant I was thinking about making a record so I still want to do that," Duff, whose most recent album, Dignity, was released in 2007, said.

"I think that after I have the baby I'll want to sit still for a few months and learn how to be a really good mom, " she continued. "And then there's no reason why I can't put a record out and tour...It might take a little while but I'm really excited about it."
