Miley Cyrus branded Lady Gaga a "scene stealer" for her entrance at the American Music Awards (AMAs) last night (24.11.13).

'Applause' singer Gaga entered the ceremony, held in Los Angeles, on a human-powered white horse, causing Miley - forgoing her usual risque attire to appear in a demure white suit - to vow to beat her at the next event. 

Speaking on the red carpet as Gaga arrived, she told E! news: "What a f***ing... What a big scene stealer! Next time I'm going to come in on a dragon.

"You can stop interviewing me if you want to go interview Gaga. I don't care." 

Miley then made reference to Gaga's entry at the Grammy awards in 2011, when she was carried down the red carpet encased in a huge egg, adding: "She didn't come up in an embryo this time. That's so boring."

Miley - who celebrated her 21st birthday on Saturday (23.11.13) - later performed her single 'Wrecking Ball' at the event, wearing a two-piece cat print bikini. She then went on to party with Amber Rose, Wiz Khalifa and Tyler, The Creator to celebrate reaching the milestone age. 

Gaga has previously said she is a fan of Miley after she stirred controversy by doing her outrageous Twerking dance move and wearing a host of skimpy outfits at previous awards shows. 

She said: "I just everybody need to lighten up and leave her alone. Because it's pop music. Everybody's entitled to their own artistic expression, and if you have a problem with it, just change the channel."
