Britney Spears: 'Carpool Karaoke was a little awkward'

 Britney Spears felt awkward singing her famous hits with U.S. talk show presenter James Corden on his hit TV segment Carpool Karaoke.

The 34-year-old was a special guest on the popular Late Show singalong on Thursday (25Aug16), but later revealed filming the episode was rather uncomfortable.

"It was a little awkward, like, driving by grocery stores," she told New York radio station KTU 103.5 FM on Friday (26Aug16). "People walk by and there are like 18 cameras around us. This is just so awkward."

Britney also confessed she has grown tired of two of her most famous tracks, 1998's ...Baby One More Time and Oops!... I Did It Again from 2000, but that didn't deter host James.

"Oh, my God... he kept playing them," she said. "He put a wig on for it (...Baby One More Time). I totally went along with it."

However, the Toxic hitmaker, who is mother to sons Sean, 10, and Jayden, nine, admitted finding out Corden was a father helped them connect during filming.

"The guy was incredibly sweet," she smiled of the 38-year-old, who shares son Max, four, and daughter Carey, one, with wife Julia. "I had no idea he has kids, he's a teddy bear. I was like, 'I just want to hug you right now.'"

The Carpool Karaoke appearance was arranged to promote Britney's new comeback album, Glory, which hit retailers on Friday, while she is also set to perform at the MTV Video Music Awards on Sunday (28Aug16) - although the pop superstar is nervous about taking to the stage at the big prizegiving for the first time in nearly 10 years.

"I still get very nervous," she confessed. "(There's) just something in the air at the VMAs, it's, like, electric. I can't really explain it. Every time I've performed there it's always been one of these nerve-racking experiences."
