Lindsay Lohan is going hip-hop on her next album – and Ryan Seacrest is impressed.

"I've heard some of it, I like what I've heard so far," Seacrest told PEOPLE backstage at KIIS-FM's annual Wango Tango concert in Irvine, Calif., on Saturday. Miley Cyrus and the Jonas Brothers performed at the show.

"Lindsay is taking it very seriously," said Seacrest, 33. "She's working really hard. She's working with great producers."

The host added, "She's told me that she's going to come in and debut the entire record with me on my KIIS-FM [radio show]. We're going to play some of the songs, and go through the whole thing together."

At the Saturday concert, Lohan, 21, told Wango Tango fans that her untitled CD (due on Motown records later this year) will include collaborations with Akon, Pharrell Williams, Ne-Yo and Snoop Dogg. An exclusive preview of her new song, ""Bossy"," was posted on PEOPLE.com last week.

The album is another sign that Lohan is getting back to work after her stint in rehab last year. She is also shooting a five-episode arc on Ugly Betty, including this season's finale, that will continue into next fall.
