Does Christina Aguilera have a grudge against Justin Bieber?

Some believe the Genie in a Bottle singer may not be very fond of him, judging by an incident that happened on the The Voice when the singer appeared to debut a sneak peak of his new video for his single Boyfriend.

After introducing the clip, Bieber jumped at the opportunity to greet the mentors: Adam Levine, Cee Lo Green, Blake Shelton and Aguilera.

When Aguilera held her hand out to shake the 18-year-olds hands, he went in for a hug and kiss on the cheek. But when Bieber went on to the next mentor, Aguilera was seen with a less-than-satisfied face.

After the show, however, Aguilera shot down any negative feelings about Bieber when she told Us Weekly "You know, he's definitely popular with the ladies and he came on the show tonight, it was a fun burst of energy. He's a really charismatic guy and it was cute!"

Meanwhile, Aguileras relationship with her boyfriend Matthew Butler is still going strong. SocialiteLife reports that duo were seen at Craigs Restaurant on April 17, with Aguilera wearing a leather jacket.
