Miley Cyrus considers Britney Spears her idol and calls her the one person that truly understands her. So when Britney kicked off her Las Vegas residency show, it was quite obvious that Miley would be present there to cheer for her. The "Wrecking Ball" singer did come to Las Vegas for the Britney show but got busy doing something else. She was caught locking lips with two of the back up female dancers of Britney, backstage! You can see the picture here.

Miley Cyrus was seated at the front row and was fully enjoying Britney as she rocked on "The Piece of Me" on stage. The 21-year-old Britney fan enjoyed the show fully by dancing and singing along with Britney Spears during the opening night of 'Britney Spears: Piece of Me' at Planet Hollywood on Friday night.

But what is Miley without controversy. The twerk queen managed to get hold of two female backup dancers and just pulled them off stage so she could do her dirty dancing with them and kiss them passionately. The whole act was caught on camera and posted on Instagram by one user named jwujek, who happened to be close to Miley when she performed her "smooch act." Check out here.

Both the dancers were probably taken aback by the sudden Miley outburst. They enjoyed the impromptu dancing and grinding with the "We Can't Stop" singer but somehow seem to just run away from her after she kissed them.

Other notable celebrities who attended and enjoyed Britney's opening night at her residency included Katy Perry, Adam Lambert, Mario Lopez and Ivana Milicevic. Celine Dion too sent flowers to the Toxic singer and Britney acknowledged everyone's presence by sending them thank you notes on Twitter.

"The most beautiful flowers I've ever seen! Thank you @Celine Dion," Britney wrote to Celine Dion.

"Was SOOOO good to see you again girl! Glad we could make our Vegas date happen :)," Britney wrote to Katy Perry.

"Love you so much! Thank you for coming to #PieceofMe ! I adore you :)," Britney wrote to Miley Cyrus for coming to her show and making headlines yet again.

Miley Cyrus not only kissed Britney's dancers but also hosted an after show party.. She co-hosted the party with showman Jeff Beacher of the famous Beachers Madhouse. The star studded event included Katy Perry, Selena Gomez, Kellan Lutz, Mario Lopez, Brad Garrett, Adam Lambert and many others.
