Bruno Mars is set to take part in 'Carpool Karaoke'.

The 31-year-old singer has reportedly agreed to join James Corden on his popular 'The Late Late Show' segment, after the TV host admitted he was one of his dream guests, E! News reports.

And Bruno - who has just released his first album in four years, '24k Magic' - is said to have already filmed the singalong segment in Los Angeles.

The release of '24k Magic' came just days after the 'Grenade' singer announced he would be heading out on a whopping 85-date world tour next year in support of the record.

The tour kicks off in Antwerp, Belgium, on March 28, and will see 'The Lazy Song' hitmaker travel around Europe before heading to North America to start a lengthy leg of tour dates from July 15 in Las Vegas, all the way through to a four-night stint at The Forum in Los Angeles on November 8, 9, 10, and 11.

Meanwhile, speaking about his ideal 'Carpool' guests, James previously said: ''I'd love to have Bruno [Mars]. Would love to do with Madonna. Beyoncé, of course.''

And earlier this week, Madonna confirmed that she will also appear on 'Carpool Karaoke' as she shared a picture of herself and James on Instagram.

She captioned the image: ''Riding around Manhattan with this Hunk of Burning Love @latelateshow carpool karaoke (sic)''

'The Late Late Show' Instagram account also shared the same picture, with the caption simply containing three praying emojis in reference to Madonna's hit singe 'Like a Prayer'.

'Carpool Karaoke' features Corden, 38, picking up a star in his car, and interviewing them whilst the pair sing along to some of their biggest hits. Previous guests on the segment have included Lady Gaga, Selena Gomez, One Direction, and Adele.
