The star and Natalie Appleton, her sister and All Saints bandmate, were seen at BBC Radio 2 studios on April 11 in London. The 39-year-old filed for a quick divorce on Tuesday morning from her Oasis musician husband under "Appleton NM v Gallagher LJP".

It was the second in a list of 12 divorce hearings set to start at 10am at London's High Court. Canadian-born Nicole and Liam's marriage hit the rocks last July after it emerged that the former Oasis singer had fathered a love child with American journalist Liza Ghorbani.
Nicole, 39, was said to have been "devastated" when she heard the news while on holiday in Florida with her older sisters Lori, Lee and Natalie. Liam was performing at a festival in Ibiza when he broke the news to his estranged wife over the phone. The couple are parents to 13-year-old Gene and married in 2008.
Nicole was bonding with her band the night before by celebrating Melanie Blatt’s March 25 birthday, a second time.
“Happy 2nd proper birthday @melblatt I love you @NatAllSaints @shiarra xxxx,” she wrote on Twitter Thursday.
Mel, 39, has been sharing snaps of the ‘90s group – which includes Shaznay Lewis - back together and doing the promotional rounds. All Saints claimed they would never reform again after breaking up in 2001, getting back together in 2006 then splitting in 2009.
However last year they announced they were the support act for the Backstreet Boys' UK tour.
