Frank Lampard’s dad pictured kissing mistress he fathered two secret children with

Frank Lampard’s dad plants a kiss on the mistress he ­secretly fathered two children with at the height of his own footie career in the 1970s.

Former Blues and England player Frank, 41, reportedly banned his dad, also called Frank, from seeing Janet Butler after the affair emerged 15 years ago.

But we can reveal West Ham legend Frank Senior is a regular visitor at her penthouse in Wanstead, East London.

And he has also been seen holding hands with Janet and enjoying meals and drinks with her at a nearby restaurant as well as at his own pub – which he bought last year and is just a few ­minutes’ walk from her home.

Frank Snr, 71, last night told the Sunday People the pair are just “big friends”.

But a source said: “Frank is often round Janet’s and they’ve been seen holding hands together. They look very close.”

England star Frank Snr secretly fathered kids Sophie and John with Janet during a long-term affair in the 1970s.

Sophie was conceived just a couple of months after Frank Jr’s birth and her younger brother John five years later, while Frank Snr lived a double life behind the back of wife Pat.

She was the twin sister of Harry Redknapp’s wife Sandra and died of pneumonia in 2008.

Frank Snr raised Frank Jr and his older sisters Claire and Natalie in Romford, Essex, and sent them to private school.

But he initially kept his name off Sophie and John’s birth certificates while they were ­growing up in a nearby terrace house, eventually adding his name when they were re-registered in 1995.

The affair was made public in 2004 – which is also when Frank Jr and his mum are understood to have found out about it.

“I’ve got a pub near her and I see her around sometimes and do keep in touch with her.

“But, no, do me a favour! Not for me, mate!”
