Michelle and Liz were pictured alongside fellow throwback pop star Lee after bumping into him at a glitzy party thrown by fashion brand Piamichi.
The event was held in London and the girls were all smiles as they caught up with their pal. Also, how fab does Michelle look considering she gave birth to her second baby just four weeks ago?!
Posting the photograph online, Michelle commented: "Great catching up with my gorgeous girl @LizMcClarnon and the ever handsome @llatchfordevans @Piamichi event x."
Michelle and Liz were reunited last year when their bands - Liberty X and Atomic Kitten - reformed for ITV2 show The Big Reunion.
But although Atomic Kitten, also made up of Kerry Katona and Natasha Hamilton, are continuing on as a group, Liberty X have decided to go their separate ways.
Atomic Kitten are certainly going to have their hands full though, as Kerry is all but ready to give birth to her fifth child, while Natasha has announced she and 5ive's Ritchie Neville are expecting a baby together!
