The next Carpool Karaoke guest is going to be the best one yet

It was only a matter of time..

Carpool Karaoke never fails to entertain us, between James Corden's brilliant sense of humour and the long list of amazing guests, we always look forward to watching the latest one. Being a guest of the show is almost like a rite of passage now for anyone who's anyone in celeb land. From Michele Obama to Adele we have had our fair share of brilliant women gracing the carpool car. So we weren't surprised to hear that the newest guest to be announced for the show is the iconic Britney Spears. Britney and James seem as excited as we do about the news. She posted the picture below to her Instagram with the caption: "Took a ride around LA with @j_corden & did a little #CarpoolKaraoke" https://www.instagram.com/p/BI70oqchON-/?taken-by=britneyspears The video will come out on August 25, the day before her new album Glory is due to be released. A while we know that Britney is there to promote her newest album we hope to hear old-school Britney tracks like Baby One More Time and Stronger with backing vocals from James Corden.  We can't wait to see it!
