Frankie couldn't resist getting a photo taken when she came across a giant image of Reading Football Club player Wayne on Tuesday (15 April).
Striking a happy pose, the starlet added the caption: "I had to."
Frankie's fans loved the snap (with nearly 10,000 favouriting it in just a few hours) and were quick to shower the couple with compliments.
"You always look super cute and stunning in all your piccies, Frankie," said one, while another joked of Wayne: "That's probably what he feels like when he sees pics of you all over London lol."
A third fan said: "So cheesy, but cute!" While another admitted: "I'd do the same!"
'What About Us' singer Frankie and left back Wayne became engaged in April 2013, shortly before announcing they were expecting their first child together.
Son Parker Bridge was born in October 2013.
The couple are now planning their big day but according to Frankie, 25, it won't be an over the top celebration. "Wayne hates being the centre of attention," she told Fabulous. "We wanted to go abroad, but with a new baby it's not worth the stress."
