Extra Rocks

Oksana Grigorieva has already dropped her baby weight -- just about a month after welcoming Lucia with beau Mel Gibson.

When asked by "Extra's" Mario Lopez how she got slim, Grigorieva says, "I don't know. Just being an active mother, I guess. It just snapped right back in."

How's Gibson as a father?

"He's a great dad," Grigorieva says. "He sings a lot to her."

Grigorieva spoke to "Extra" the same day her single "Angel" -- from her album "Beautiful Heartache" -- was released on iTunes.

She plans to donate the money from the downloads to a charity close to her heart, Chernobyl Children's Project International. Learn more about the charity here.

Hugh Dillon has branched away from his hit band, The Headstones, to make music on his own -- and Dillon, 46, just dropped the music video for his single, "Ten Feet Tall," from his solo album.

The singer's talents don't stop onstage -- Dillon has dabbled in acting, and has created original musical pieces for projects he's worked on, including "Durham County" and "Flashpoint."

Dillon's album, "Works Well With Others," is currently available on iTunes.

Jim Weatherly, the man who wrote "Midnight Train to Georgia," sings the original version just for you. Check it out!

Nick Jonas is going solo!

The Jonas Bro, 17, has started his own band, his mom confirms to Parade.com.

"Nick is working on a solo act -- it's called Nick Jonas and The Administration. Shhh!" Says his mother, Denise Jonas. "He's at the photo shoot for the album cover right now."

Denise also reveals that her son Kevin Jonas, 21, has set a wedding date with fiancée Danielle Deleasa.

"Kevin and his fiancée Danielle have set their wedding date -- but it's completely private," Denise teases.

She's a fan of Deleasa, to whom her son became engaged to in July.

"Danielle, bless her heart, is from a great little Italian family. She is everything I ever prayed for and hoped for Kevin," she said.
