Carnie Wilson: Curvy and proud of it.

Buoyed by a string of successful one-off gigs at select Wal-Mart stores across the United States, '90s group Wilson Phillips is getting back into the recording studio to work on songs for a new album, slated for release in late Fall next year.

The light pop/rock trio, who soared to worldwide fame on the strength of its 1990 monster single "Hold On," is also actively looking for new creative ways to showcase perennially curvy member Carnie Wilson in videos and photo shoots without drawing too much attention to her weight.

"We've accepted that Carnie is never going to be slim and sexy like myself and Wendy," said Chynna Phillips, daughter of John and Michelle Phillips of The Mamas & The Papas. "So we're just going to do what we've always done and hide her curviness, but in ways we haven't done before."

Phillips admitted that it's "going to be a tall task this time around."

"We've stuck her behind couches, stood in front of her, put her next to large barrels," Phillips said. "And you can only do those tricks so many times. We need to come up with something fresh and innovative."

In terms of the music the group is working on, Wendy Wilson said they are going in a completely unchartered musical territory, but longtime fans need not worry because "it will still have the same old Wilson Phillips vibe."

"We just want to shake things up a little by trying out some edgy stuff with Linda Perry," said Wilson. "This is what I truly enjoy about this job, to be able to do something cutting edge and totally unexpected."

Among the tracks the group intends to include on the new album is a song called "She Ain't Heavy, She's My Sister" which incorporates elements of The Hollies' "He Ain't Heavy, He's My Brother." Wendy Wilson said she pitched the idea as a tribute to her older sister Carnie.

"I wanted to show Carnie that I love her no matter what her waist size is, and the song sums up how I feel," said the younger Wilson and daughter of the Beach Boys lead singer Brian Wilson.

The trio's last studio album, a collection of cover songs, was released in 2004.
