She was given the honour of closing the show at the show at Capital FMs Summertime Ball and Katy Perry ended the night in style.

Katy sported a black bobbed wig with fringe for the occasion and matched her unusual outfit with flat shoes, no doubt so she could keep up with the dance moves.

A group of flamboyantly dressed backing dancers with brightly coloured wigs helped the performance go with a bang.

Meanwhile, the fun loving popstar was planning to celebrate her performance with an aftershow date night with Florence + The Machine guitarist Robert Ackroyd.

The couple first met at Californias Coachella festival in April and enjoyed a brief romance before splitting last month.

However, they rekindled their romance when Katy recently jetted in to London and have been spotted on a number of dates in the English capital, including dinner dates in East London.

Yet after her performance at the Summertime Ball, the kooky songstress had a different type of date in mind and booked a bowling alley down the road from Wembley so they could enjoy a laid back evening.

A source told The Sun Katy has always loved taking her dates for activities like bowling and skating.

While things are going well in her personal life, Katys professional life is also thriving and it has emerged a move into feature films could be on the cards.

The 27-year-old popstar has been linked to the role of Fre! ddie Mer cury's girlfriend Mary Austin alongside Dictator star Sacha Baron Cohen in a new movie about the Queen singers life.

A friend of Katy told the Mirror: Katy would love to be in the film as she is such a huge fan. She would want to play Mary Austin ideally. Katy has a similar look to Mary and would be a brilliant foil to Sacha.
