Julianne Hough and Christina Aguilera are apparently two of Hollywood’s most feisty starlets! The Burlesque co-stars ran into each other at a CAA party Jan. 14 at West Hollywood’s Soho House, where Christina reportedly grabbed Julianne’s arm!

“Christina really got in her face,” a source tells E! Online. “This whole thing was troubling. People felt bad for Julianne.”

The two reportedly didn’t get along while filming Burlesque and it’s evident there are still unresolved issues.

Christina’s reps say the report is “nonsense.”
