She may have flown in from Los Angeles just hours earlier after a whirlwind trip Stateside, but there was no sign of jetlag on a glowing Cheryl Cole's face on Saturday.

The singer, 29, was dressed in her best as she met fans at an intimate book signing for her autobiography My Story at a central London hotel.

The Girls Aloud star showed off a hint of her flat stomach in an unusual dress with nude crossover wrap top and ruched orange skirt.

The Geordie star teamed her look with a pair of spiked nude heels and dangling earrings, with her hair swept back into a high ponytail.

Only a select group of fans and just one photographer were in attendance for the Waterstone's signing event at the Corinthia Hotel - which is where the X Factor contestants are staying.

The lucky fans who got the chance to meet Cheryl at the exclusive two-hour event had bought limited 20 tickets, which includes a copy of the book.

The signing meant Cheryl was back to her solo artist persona after spending the past few weeks reunited with her Girls Aloud bandmates.

Unfortunately, the five-piece's comeback track Something New was pipped to the No.1 spot in the UK singles chart by Olly Murs.

Following heavy promotion of the single on Children In Need, Strictly Come Dancing and the Royal Variety Show, Cheryl has spent the past few days in Los Angeles.

It's been reported she paid a visit to former boss Simon Cowell's mansion, prompting speculation she could return to X Factor UK.

However, a source told the MailOnline: 'They have met a few times in the last 18 months and have remained in contact. They were just shooting the breeze and catching up.'

Accompanying Cheryl on the trip was her American boyfriend Tre Holloway.
