Nelly's duet with Kelly Rowland has hit the top of Britain's singles charts - giving the rapper his first UK number one.

UK act Big Brovaz have also charted high, with their first single Nu Flow entering at number three.

On the album charts, Will Young has held on to the top spot with From Now On - part of an unchanged top four.

Nelly was born in Texas, and had a surprise album hit in the US with his first release, Country Grammar, in 2000.

It entered the Billboard album chart at number three before climbing to the top and spending five weeks there.

Dilemma sees him duet with Destiny's Child's Kelly Rowland, no stranger to the number one spot with her usual bandmates.

John Otway's Bunsen Burner, which gave the singer a number nine after 25 years away from the charts, has fallen out of the top 40.

Norah Jones: Remarkable sales for a jazz singer

Will Young's album From Now On features several songs written by Young as well as the chart-toppers Anything Is Possible/Evergreen and his cover of The Doors' Light My Fire.

It is in its second week at number one, holding off a new compilation of the Rolling Stones' greatest hits, Forty Licks.

Another hits collection, Elvis Presley's, is at number three followed by jazz singer Norah Jones, whose album Come Away With Me has sold more than 300,000 copies - a rare event in the jazz world.

Two more collections - by Fleetwood Mac and INXS - have also entered the album top 20.
