Christina Aguilera 'denies Ronson rumours'

Christina Aguilera's representative has denied rumours that the singer is dating DJ Samantha Ronson.

The 29-year-old singer announced her separation from husband Jordan Bratman earlier this month, and filed for divorce shortly afterwards.

Star reports that rumours have been circulating regarding Aguilera's relationship with Ronson, after the pair were spotted spending time together following last week's announcement.

However, a representative for Aguilera told the Chicago Sun-Times: "[It is] a good, longtime friendship and nothing more than that."

Ronson previously dated Lindsay Lohan on and off from 2008 to 2009.
