BBC 1Xtra's Zena is leaving the breakfast show which she co-presents with Trevor Nelson. Her last show on the national digital station will be this Friday.
The presenter joined the station last October as part of a revamp of the schedules.
Zena is moving across the United States with her husband, former Charlton footballer Cory Gibbs, who has been signed to the American MLS Football League.
Head of Programmes Lorna Clarke says: "Zena had no radio experience before joining 1Xtra and made an immediate impact with our audience on the breakfast show as co-host with Trevor Nelson, one of the UK's most experienced broadcasters.
"I know the audience will miss her banter and entertaining take on life and, above all, her passion for music."
Trevor Nelson says: "I'm just gutted that Zee is leaving. We have a special on-air chemistry, which is so hard to find.
Zena, who also co-presented the 1Xtra Loves Summer shows in Crete and Ibiza, will be replaced by a new co-host in the autumn.
