The proud new mother, 24, and her fiance, football player Wayne Bridge, 33, can be seen in the Instagram photo kissing the head of their three-week-old son.

Frankie captioned the photo: “So much love.”

Fans of The Saturdays were quick to gush over the new-born, with one posting: “Congratulations, what a beaut,” while another added: “Such a pretty baby.”

Disco Love singer Frankie announced their son’s arrival on Twitter last month, posting: “Wayne and I are so proud to say our little boy Parker Bridge was born this morning. 7lb 13oz. All doing well and absolutely besotted.”
