Meghan Trainor has had some pretty big highs in her career so far, but none of them scream "life goals" as loudly as getting to sing with the Backstreet Boys. 

As part of ABC’s Greatest Hits show on Thursday night, Meghan joined AJ McLean, Howie Dorough, Nick Carter, Kevin Richardson and Brian Littrell on stage to perform every 90's kids' go-to party song I Want It That Way.

And not only did the songstress successfully sing with the lads without keeling over fangirl-style, Meghan even managed to keep up with their dance moves.

In a behind-the-scenes video the All About That Bass singer revealed that, like all of us, the first band she ever loved was the Backstreet Boys.

She said: “The first band that I loved was the Backstreet Boys.”

“My pop star crush was Brian [Littrell].  I was gonna marry him and my mom was gonna marry him.  That was our husband.”

“The day he got married, I remember we were like, ‘Nooo!’”

The 22-year-old star went on to describe performing with the band as a "bucket-list moment".

On the night, the lads also sang Everybody to an enthusiastic crowd.

To say we are jealous of Meghan, the Backstreet Boys and basically every person in that audience is a major understatement.
