According to Heat, the TV presenter wears various outfits to make sure things do not get boring in her relationship with the Chelsea midfielder.
"They keep things fresh," a source told the magazine. "Christine knows how to keep Frank happy. Sometimes she'll even dress up.
"Christine's always driven men wild. She definitely knows how to push their buttons, and Frank's no exception."
A supposed friend added: "Christine has said they've got a great physical connection. She said she goes to bed smiling every night.
"They have the same sense of humour, but they're both really intelligent, too. They're an equal match... Frank's money doesn't intimidate her. She's very independent. Christine's his dream woman."
It has been claimed that Lampard is planning to to propose to Bleakley and that the pair have been seen together several times in the congregation of Ballyblack Presbyterian Church in her home town of Newtowonards, Northern Ireland.
