Cheryl and Nicola set to reunite Girls Aloud with Kimberley and Nadine on stage at The O2

Cheryl and Nicola put on united front as they tease Girls Aloud reunion with Kimberley and Nadine

Cheryl and Nicola Roberts have sparked speculation that Girls Aloud could be reuniting as they arrived at The O2 for rehearsals together.

The pair looked excited as they greeted each other with a hug after arriving separately at the iconic London venue on Friday.

It comes after Nadine Coyle and Kimberley Walsh were spotted arriving at the arena on Thursday.

The band have not performed together since their Ten: The Hits Tour in 2013, but have been teasing a reunion for the past few weeks.

Nadine Coyle sparked the rumours last month by confirming that the band were planning to get back together for a 20th anniversary tour.

Cheryl has since hinted that the reunion is definitely on the cards, saying that she 'wouldn't say no' to a tour.

However, it is not yet known whether Sarah Harding will be able to take part in the reunion.

The star was diagnosed with breast cancer in August 2020 and has been undergoing treatment.

Girls Aloud were formed on the ITV show Popstars: The Rivals in 2002.

The group went on to become one of the most successful girl bands of all time, selling over 4 million records in the UK.
