Sometimes, having a new guy or gal on your arm can be the most effective ego boost out there, and that's exactly what Californian rock band Train have tapped country star Cam and Gym Class Heroes' frontman Travie McCoy to sing about on their fun-loving new track, "Call Me Sir." Though the release is Train's, every featured artist gets their own verse on the track. Readers can press play above to listen.

"I ain't goin' nowhere unless he's there with me / 'Cause I don't stand in line no more / Admission's always free," Cam sings during her part of the track. "He could break the law, he could break your heart in two / But I promise that you won't care / When he smiles at you." Over a pop-heavy guitar riff, the lyrics tell a story of lover that comes with so many social advantages -- and so much charm -- that it doesn't matter how much they may misbehave in other areas.

"It's a true story, and I love what [Cam and McCoy] bring to the song," Train frontman Pat Monahan says in a statement, according to Billboard. "I hope everyone will like this one as much as we love performing it."

It isn't the rock band's first time finding collaborative partnership in the country world. The group has collaborated with country and Americana heavyweights such as Martina McBride (on CMT's Crossroads Series in 2010) and Ashley Monroe for the song, "Bruises," off of Train's album, California 37.

For her part, Cam has spent this spring on her intimate Listening Room Series Tour. Her latest single, "Diane," was released in February of 2018, and is the first taste of her upcoming sophomore album.
