Cardi B has let her hair down ahead of Longitude - literally! - but it looks like she might have regretted her decision to fling her wig into the crowd at a festival in London.

The New York rapper, who is headlining the Sunday night of Longitude in Dublin's Marlay Park, was performing at London's Wireless Festival on Friday when she ripped off her wig mid-song and threw it into the audience.

She later took to Twitter to appeal for the return of the lustrous hairpiece, writing: "I GOT CARRIED AWAY .......I want my wig back:/ Dm me."

Fans replied and advised the Grammy-winning star to check eBay to see if it was being sold.

During her headline slot at the London festival, Cardi B brought out rapper Lil Nas X for a surprise guest appearance and performed his breakout hit Old Town Road.

She later thanked the 20-year-old rapper and predicted a bright future for him, tweeting: "I'm going to bed I have such S bad headache .I want to thank @LilNasX for coming out tonight at Wireless !

"It was lit keep doing your thing ,the stars is the limit .....Stream rodeo for a date with lil nas. (sic)"
