Christina Aguilera has shared her sympathies with fellow singers Blake Shelton and Gwen Stefani, who have reportedly struck up a new romance after splitting from their spouses.

The Genie in a Bottle singer is a rotating judge with the pair on TV talent show The Voice, and knowing first-hand how painful a split in the spotlight can be, Christina is supportive of the stars and their rumoured relationship.

"I do know from my own personal experience how difficult divorce can be," she says to Entertainment Tonight about her split from Jordan Bratman after five years of marriage. "All I do know - from knowing Blake from so many seasons past... and knowing Gwen for even longer than that, going to each other's kids' birthday parties, etc. - they're great people."

Christina, who has since had a second child with fiance Matthew Rutler, adds, "They deserve happiness, especially when you have to deal with a lot of the press c**p and everything."

Blake and fellow country star Miranda Lambert announced their split in July (15), while the No Doubt frontwoman and rocker Gavin Rossdale shared their divorce news in August (15). A representative for Gwen recently confirmed the singer is dating Blake.
