Nadiya Bychkova, Sinitta and Alexandra Burke looked sensational as they led the star arrivals at the Spring Ball at London's Lio on Wednesday. Strictly Come Dancing's Nadiya, 34, left very little to the imagination as she attended the star-studded event braless in a sheer pink sparkly dress. The Ukrainian native channelled her inner glitter ball as she paired her sequin garment with a silver clutch and sparkly silver heels. DJ Sarah-Jane Crawford, 40, looked pretty in pink as she wore a sweet floral pink summer dress. The radio personality also looked radiant as she paired her spring look with a pair of sparkly silver heels.
