How’s Miley Cyrus getting mentally prepared for her big New Year’s Eve show in Times Square? By going to Vegas and watching Britney Spears perform, obviously. Miley sat front row center for Brit Brit’s big Las Vegas debut and the 21-year-old couldn’t believe her luck.

if u told me I'd be front row & center on @britneyspears opening night 10 years ago I wouldve never believed you,” Miley tweeted alongside a photo of her at the show. Miley’s tongue’s hanging out so you know she liked it.

She also shared a closeup of Britney during her Piece of Me show with the diva rocking a black leotard we’re sure Miley would love to borrow. “Dreams to come true @britneyspears lookin BANGIN,” Miley wrote, so excited we’re thinking she accidentally switched out a “t” for a “d” in the message.

We’d heard Miley was likely to attend Britney’s opening night. Also in the audience: fellow pop diva Katy Perry who shared her excitement via typo-heavy tweeting, too: “Soy excited to see @britneyspears baby bottle pop it off tonight at her grand opening @phvegas! We are coming in full lewks to support!

Although neither songstress joined Brit onstage, Miley still managed to stress her voice, later tweeting that she’s got “an obnoxious cough that won't go.” Thankfully girlfriend decided to call it a somewhat earlier night yesterday. Good thinking. Hate to be hoarse for Ryan Seacrest.
