Rocker Adam Lambert wants a duet with Burlesque star Christina Aguilera and his first celebrity crush was on actor Leonardo DiCaprio.

The Grammy-nominated singer put on a quick media tour before Sunday's Grammy Awards.

Lambert's hit single Whataya Want From Me received a Grammy nomination in the Best Male Pop Vocal Performance category. The single appears on Lambert's debut studio album For Your Entertainment.

During an interview on CBS' The Talk, the 29-year-old American Idol season 8 runner-up said he would like to work with David Bowie and Beyonce.

Last year, in a segment aired on Extra, Lambert said he wanted to perform with Christina Aguilera.

When host Mario Lopez asked, “If you could do a duet with anyone, who would it be?” Lambert responded: “Right now I'm having this fantasy about singing with Christina Aguilera.” (The video is embedded in the right panel of this page.)

Lamber was also asked by a fan if he had ever dated a woman.

“No,” Lambert answered, then added, “But you never know, though.”

He revealed his first celebrity crush was on actor Leonardo DiCaprio in the movie Romeo and Juliet.

“But no one knew, I kept that very private,” Lambert said.

UPDATE: This version adds that Lambert made his comments last February.
