'No Regrets' is No. 1
N-Dubz singer Dappy has gone solo and bagged himself a chart topper with his first solo single.
Rich + Kat broke the news to Dappy when he joined them on Sunday's Vodafone Big Top 40 and it's fair to say, Dappy got pretty excited.
He screamed, he jumped, he fell off his chair... and we caught it all on camera.
Take a look at that awesome moment when Dappy found out he was No. 1...
It was a big week for new entries in the top ten, James Morrison's new single 'I Won't Let You Go' flew straight in to our chart at No. 7 and 'It Girl', the new song from (sing it) Jason Derulo was new at No. 6.
There was also a surprise appearance for Damien Rice in the top ten thanks to maths teacher, John Adams' audition on Saturday night's X Factor.
