Usher keen to collaborate

R&B singer Usher has admitted that he is keen to collaborate with fellow superstars Lady Gaga and Britney Spears, who have both expressed an interest in working with him.

Discussing a duet with Spears, he explained to Access Hollywood, "I think it would be great. We've actually talked about working together in the past."

The 31-year-old star also added, "I've actually shown some interest in working with Lady Gaga as well. We spoke about it the other night and may potentially make something happen there in the future."

Usher releases the deluxe edition of his 'Raymond V. Raymond' album on September 20.
