Sevyn Streeter has a hot single with Chris Brown currently making its way up the charts and has written major hits for the likes of Ariana Grande and Kelly Rowland. Are you ready for what's 'nEXT' from the rising R&B star?

Sevyn, who's set to release debut EP 'Call Me Crazy, But...' on Dec. 3, is giving PopCrush readers an exclusive first look at an audio preview of her new song, 'nEXT.' It is the first of seven mini music videos being released in anticipation of the EP, which is available to pre-order beginning today (Nov. 5) here.

The 'nEXT' clip co-stars actor-musician Tristan "Mack" Wilds of 'The Wire' and '90210' fame. It shows the photogenic pair cuddling and taking photos in happy times, intercut with a sad and single Sevyn singing, "How can my ex-boyfriend be my next boyfriend?"

The video for Streeter's current single with Brown, 'It Won't Stop,' currently notches more than 3.5 million views on YouTube. (Watch it here.) She also has written Brown's 'Fine China,' as well as Grande's 'The Way' and Rowland's 'Gone.'

Sevyn is currently touring with her label mate K. Michelle. For more info, visit here site!
