Sinitta, 58, commands attention in a pastel pink unbuttoned shirt and jeans as she attends Wicked

Sinitta commanded attention in a pink ensemble as she attended the new Wicked opening night at the Apollo Victoria Theater in London on Thursday.

The 58-year-old singer put on a stylish display in a pink and black shirt which she wore unbuttoned, showing off her toned midriff.

She stood out from the crowd in a pair of pink wide leg jeans which she teamed with Louis Vuitton high heels.

The former X Factor favorite opted for a large black shoulder bag and kept her Wicked schedule before the show started.

She accessorized with a simple pink ring to match her outfit and flashed her diamond belly button jewelry.

Sinitta completed her look by styling her raven locks in soft waves while adding a smokey makeup palette that included a pink lip.

The So Macho hitmaker beamed as she posed at the star-studded event alongside Perrie Edwards, AJ Pritchard and Abbie Quinnen.
