Nelly pursuing Aguilera on video set

Hip-hop star Nelly has been infatuated with Christina Aguilera since the pair duetted together on their forthcoming single Tilt Ya Head Back.

The Hot In Herre rapper plays a 1940s gangster opposite Aguilera's sexy Marilyn Monroe lookalike in the video that accompanies the track.

And, according to a spokesperson at record label Universal Music, the atmosphere between the stars was so electric on the set of the promo - it was obvious Nelly fell in love with the Dirrty singer, who is dating Jordan Bratman, an employee at her management company.

Beverly Berringham, a spokeswoman for Nelly's Dirrty Entertainment firm, says the rapper gave Aguilera a gift of €44,000 worth of jewels as a parting present.

Universal say during filming the pair "looked at each other with lusting eyes".
