EXCLUSIVE VIDEO INTERVIEW: LL Cool J On Grammy Nominees Justin Bieber, Lady Gaga & Katy Perry

So what's LL's take on Bieber, the pop culture phenomenon who's stolen the hearts of tween girls everywhere, en route to a nomination for best new artist this year?

Justin Bieber's "really blessed," LL told us exclusively at a private party at West Hollywood's Gendarmerie spa.  "As a guy who started really young in hip hop," LL said he faced a "similar kind of experience" on his way up the charts.

"I can definitely related to Justin Bieber, and I'm really happy for him," the Mama Said Knock You Out singer said.

LL said he was happy for Eminem's critical successes rivaling his commercial ones, as the Detroit based rapper's up for a career-high 10 Grammys.

"We weren't eligible for Grammys for most of my career," he said. "To see him nominated for 10, that means we're moving in the right direction."

The NCIS: Los Angeles star said Lady Gaga, who's up for six honors, is "tremendously creative, and skilled at selling the unconventional.

"Unlike some people, she doesn't wear you out with it -- it doesn't get old," he said of the Telephone singer.

Katy Perry's Teenage Dream got a nod for best album of the year, and LL said that the "California gurl" should be primed for more honors in her career, as she possesses an arsenal of qualities key in making a successful pop star.

"Katy Perry is amazing," LL told us. "She's pretty, she's talented, she's smart she can sing.

"The sky's the limit."
