Miley Cyrus has no qualms about lending her boyfriend, [article id="1597775"]Justin Gaston[/article], out to newly single friends, like Taylor Swift. On Wednesday night, the pop star attended the CMAs in Nashville alone so that Swift could use Gaston during her performance at the awards ceremony.

"I'm flying solo tonight," Cyrus told People.com on the red carpet. "Justin is making an appearance in Taylor's song. But that's OK, because it means my two best friends are onstage at the same time!"

During Swift's performance of "Love Story," Gaston reprises his role of Swift's Prince Charming-like love interest, a part he played in the song's video. But the only thing on Gaston's mind was his real-life love interest, Cyrus, who [article id="1599176"]recently shot a video for her single "Fly on the Wall."[/article] "I saw [Miley] briefly," Gaston told the site. "She really looks pretty."

It was a family affair for the Cyruses, as the singer's dad, Billy Ray, was also there, and he only had great things to say about his daughter's boyfriend. "Can you believe how far this kid has come?" Billy Ray said. "Just a few months ago when I first saw him perform on 'Nashville Star,' I said he was going to be a big star. He's got it all -- talent, looks, personality. And look at him! Look where he is now!"

Both Swift and Miley Cyrus are former Jonas Brother girlfriends, so it comes as no surprise that they are good friends. After her [article id="1592354"]breakup with Nick Jonas[/article], Miley told Seventeen magazine, "Nick and I loved each other. We still do, but we were in love with each other. For two years he was basically my 24/7. We were arguing a lot, and it really wasn't fun."

Meanwhile, Swift has been vocal the past few weeks about her [article id="1599032"]breakup with Joe Jonas[/article], who she said [article id="1599248"]left her for his current girlfriend[/article], his "Lovebug" co-star, Camilla Belle. "They've been together since we broke up," Swift told the USmagazine.com at the awards show. "That's why we broke up -- because he met her."
