When two female pop superstars get together, the results are normally enough to make you pray for a ruptured ear drum. Remember Mariah trying to out-warble Whitney on 'When We Believe'? How about Barbra baying for Celine's blood on 'Tell Him'? And, frankly, the less that's said about VH1's Divas Live concerts, the better.

'Beautiful Liar' isn't as ridiculously overblown as those collaborations, but it's as calculated as a wannabe page 3 model's decision to have a boob job. It has a stuttering R&B beat to keep Beyonce fans happy, some middle-eastern instrumental hooks to let us know that Shakira's, y'know, a world music sensation and a video that features gratuitous belly-wiggling. It's not bad, but the only people who've really excelled themselves on this one are the make-up artists who powdered those lovely tums.
