Hilary Duff blonde singer disney the grove mario lopez

She's beginning to show!

Hilary Duff stopped by the Grove to chat with Extra's Mario Lopez about her growing baby bump, and her new book, 'Devoted: An Elixir Novel'.

The momma-to-be has been busy making appearances all over the country to promote her second novel, and at four months preg, that can't be an easy task!

The former Disney star recently revealed on Ellen this week that she's expecting a boy, and she's already come up with a few possible names for the little guy.

Hil revealed to Access Hollywood on Friday, “Before I even got pregnant, I had a list. We have a few [names,] we’re kind of debating and going back and forth. We’re thinking were going to go either traditional middle name and unique first name, or we’re just going to go super traditional. We’re up for suggestions!”
