The `Sweet Dreams` singer - who wowed crowds with a performance of her latest track while wearing a skimpy red corset and suspenders - was the most successful star of the night as she was awarded the prize for Best Song for her track `Halo`, Best Video for her hit record `Single
Ladies (Put A Ring On It)` and also scooped the Best Female Singer honour.

The 28-year-old beauty`s win completely overshadowed Lady Gaga, who had been nominated for five awards but only went home with the Best New Act prize.

Ceremony presenter Katy Perry, 25, was so starstruck by the singer-and-actress, she almost "p****d" herself with nerves and excitement when they met.

The `I Kissed a Girl` singer admitted she was terrified about running into the curvy singer and fellow chart-topper Lady Gaga in case they judged her on her skimpy stage outfits and cheeky presenting style.

She said: "I?m totally petrified about what those girls will think, but I?m doing it in my own way, not to be taken too seriously - like everything I do.

"I saw Beyonce and nearly p****d myself - she`s such a force."

Busty brunette Katy - who changed her outfit 12 times during the ceremony - teased the crowd with a host of sexy anecdotes and at one stage, even joked about the ?Poker Face? star - who has been plagued by rumours she is a hermaphrodite.

Sitting in a giant, red, glittery stiletto, she quipped: "They say if men have big shoes, they have big? The confusing thing is I borrowed this from Lady Gaga!"

The `Paparazzi` singer was not the only act left disappointed last night. Rockers Kings of Leon also left empty handed despite also being nominated for five prizes.

However, the night was deemed a huge success by rapper Jay-Z, who won the Best Urban award and Irish rock band U2, who were given the Best Live Act award.

The renowned music acts raced to the ceremony together after the US superstar made a surprise on-stage appearance with the rockers in front of 10,000 fans at Brandenburg Gate.
