Saturdays star Una and her husband Ben welcomed son Tadhg into the world earlier this month and bandmate Frankie has described the tot as "gorgeous".
During their meet up yesterday (17 February), Frankie took a sweet picture of her son Parker playing with Una and Ben's eldest child, daughter Aoife.
Sharing the snap on Instagram, she said: "It was so good to see @unathesats today! Little Tadhg is gorgeous, of course, and was so lovely to see these two playing and having so much fun together #satsfamily."
The Sats family is fast expanding. As well as Aoife, Tadhg and Parker, Frankie and her footballer husband Wayne are expecting their second baby together.
And then there is little Alaia-Mai, Rochelle and Marvin Humes' daughter.
There is definitely enough of them to form a new band now!
