Una's daughter Aoife Belle and Michelle's little girl Faith had a play date this week and, luckily for us, Una tweeted a picture of the pair playing.
Michelle replied: "Undoubtedly two of the most cutest little girls ever! #babyfaith & Aoife Belle! Thank u @UnaTheSats for having us.."
No doubt Una and Michelle had plenty to talk about during their girls' playdate with both mums currently wrapped up in brand new TV shows.
Una and The Saturdays are starring in E! reality show Chasing The Saturdays, which documents their attempts to crack America, while Michelle and the rest of Liberty X have reunited for ITV2's hotly-anticipated The Big Reunion.
We can't wait to see both!
