Well, this is awkward. The feud between Jay-Z's longtime pal Kanye West and his new summer tourmate Justin Timberlake has intensified -- so which side will Jay choose?

Things haven't gotten completely out of hand just yet, but during Justin's performance on this weekend's Saturday Night Live, the singer did take a blatant dig at Kanye in response to comments the rapper made at a concert last month. Click after the jump for all the deets!

If Taylor Swift made one thing abundantly clear in her performance at the 55th Annual Grammy Awards, it's this: she is never, ever getting back together with Harry Styles. Like ever.

Taylor made a blatant diss towards her most recent ex-boyfriend during the performance of the hit song when she said, "So he calls me up and he's like, 'I still love you,'" in a British accent. To dig the knife in Harry's heart just a little deeper, she continues, "And I'm like, 'I'm sorry, I'm busy opening up the Grammys!'" HA!

Demi Lovato may not always see eye to eye with Simon Cowell on The X-Factor, but she definitely supports the ladies of Fifth Harmony, the group Simon has mentored all the way to the show's finals.

During Wednesday night's final performances, country stars LeAnn Rimes and Little Big Town were brought in to sing with Carly Rose Sonenclar and Tate Stevens, but Fifth Harmony got a little help from right at home when their idol Demi joined them on stage for a performance of Give Your Heart a Break! AND it may have been just what the girls needed to prove that they've earned their spot in the top three!
