The 'Bleeding Love' singer turned 28 and she marked the occasion by hosting a house party, reported Contactmusic.
Lewis gave the bash a 1990s theme and instructed guests to wear fancy dress. She embraced the retro look by turning out in high-waisted, stone-washed jeans and a midriff bearing pink crop top, while former Sugababes star Keisha Buchanan was pictured wearing denim dungarees and a bandana.
Buchanan posted pictures from the party on her Twitter page, with the caption, "Happy Bday (birthday) Leona!!! Love you loads. House party (sic) 90s. Old school garage. Hip-Hop. Dance... Fancy dress. Fun times.
