Courteney Cox threw a party to celebrate Barack Obama's success in the American presidential election on Tuesday night.

Amy Winehouse and Mark Ronson are reuniting to record a song. The pair fell out when recording sessions for a proposed James Bond theme went sour - which resulted in Jack White and Alicia Keys providing the opening music to "Quantum of Solace" - but have since settled their differences and are planning to record a track for a tribute album to Michael Jackson producer Quincy Jones.

A source said: "It's going to be explosive stuff. Amy first met Quincy backstage at the Nelson Mandela show in Hyde Park in June."

Usher says having a child has improved his life. The "Yeah" singer - whose wife Tameka Foster gave birth to the couple's first child Usher Raymond V last November - is surprised by how much parenting has affected him.

Usher is reportedly set to become a dad again.

The "Yeah" singer and his 38-year-old wife Tameka Foster - who are already parents to nine-month-old son Usher Raymond V - are reportedly expecting their second child together, a source close to the singer has revealed.
