Alexandra Burke celebrates her 21st

Alexandra Burke celebrated her 21st birthday with a star-studded bowling party yesterday (25.08.09).

The X Factor winner - who is preparing to release her highly-anticipated debut LP this October - spent the evening at London's exclusive Shoreditch House with friends, family and celebrity pals.

A source said: "The bowling party was all Alexandra's idea - she just loves 10-pin bowling.

"It was a fantastic night. Alex and the label opened up a £10,000 bar tab so everyone could really let their hair down."

Guests including British TV presenter Myleene Klass and former X Factor contestants JLS, Ruth Lorenzo and Laura White.

However, they will be expected to do it again later this year when Alexandra throws a second birthday bash.

The source explained: "Like the queen, Alexandra is actually having two birthday parties - one last night and one in October to coincide with the new album launch. She decided to treat herself to a Stella McCartney outfit, Christian Louboutin heels and a Tiffany ring."

Although the X Factor judges were unable to attend the party, Simon Cowell, Dannii Minogue and Cheryl Cole overwhelmed the singer with their generous birthday gifts.

A source said: "Alex was in tears. Things just couldn't be better for her."

Girls Aloud singer Cheryl, who was the singer's mentor on the TV talent show, wished Alexandra a happy birthday over the phone and splashed out £5,000 on a luxurious holiday.

The generous star has booked Alexandra in to the Constance Lemuria resort in the Seychelles - the same exclusive hotel she honeymooned at with her soccer husband Ashley Cole in 2006.

Music mogul Simon treated Alexandra to a £7,000 Chanel handbag, while Australian star Dannii sent her a grey Tabitha bag.
