Joss Stone is recording a song for U.S. democratic presidential candidate Barack Obama.

The "Fell in Love With A Boy" singer was reportedly asked to lend her voice to the song - which will be used as a theme to Obama's election campaign later this year - because she will appeal to voters of all races.

Joss Stone headbutted her half-brother after an argument at a family christening. The "Fell in Love With A Girl" singer angered relatives after arriving 30 minutes late to the baptism of her godson Louis - half-brother Daniel Skillin's son.

A guest revealed: "She was absolutely furious when Daniel confronted her and they had a full-blown argument. They were screaming at each other and, the next thing, she headbutted him."

Nelly and Ashanti are "definitely very much still together." The 'Hot in Here' rapper and 'Foolish' singer - who have been romantically linked since 2003 - are still reported to be dating, despite rumors they had split up earlier this month.

Reports their relationship had ended emerged when Ashanti was quoted as saying, "I'm dating my new album, and no-one else," but the 27-year-old singer has since insisted she was misquoted.

Joss Stone is reportedly dating Nelly. The British soul singer has been on several secret dates with the 33-year-old rap star - who is 12 years her senior - and is said to be smitten with him.

A source revealed: "Joss and Nelly have been out on a few dates. It's early days but Joss is really happy. It's great that she has met someone as successful as she is and who understands the pressures of being a performer."
