Wonder what Miley Cyrus has to say?
The 19-year-old star was in Las Vegas over the weekend presenting for iHeart Radio, and while she was busy being twinsies with Gwen Stefani, her ex-BF Justin Gaston took a walk down the aisle.
On Saturday, 24-year-old Justin wed Melissa Ordway in a private ceremony at a church in Atlanta. Miley and her underwear model ex-BF dated for nine months when the starlet was only 16 years old, before she got back together with her other ex, Nick Jonas.
Miles has since settled down with her current beau and fiancé Liam Hemsworth, but although the couple has been engaged since June, they have yet to move forward with any wedding planning (Miley told us she's concentrating on her album).
The Hunger Games hunk and his fashionable fiancée met on the set of the film The Last Song, where they also costarred with—wait for it—Melissa Ordway, Justin's new bride (talk about six degrees of separation!).
The newly blond babe's ex-beau happened to say "I do" just one day after Miley and Liam were snapped cruising around in their fancy new sports car, although the famous exes were thousands of miles away on the big day.
Justin met Miley back in 2008 when the aspiring country singer was a contestant on Nashville Star, hosted by Miley's father, Billy Ray Cyrus.
Needless to say, the exes' four-year age difference (Miley was only 16 and Justin was 20 at the time) was a tad scandalous.
Hmm…why so mum, Miles? We know you love social media.
So where's the appropriate Twitter congrats?!
