The 25-year-old singer is set to go on a romantic date with the hunky sportsman after weeks of flirting on the social networking site, reported Daily Star online.
"Mollie and Stuart have been following each other on twitter for a while. They've been chatting in private on twitter and have really hit it off. Stuart has told close friends he plans to take Mollie out for dinner this Saturday," a source said.
The 26-year-old cricketer is currently in London playing South Africa and wants to make the most of being near to blonde beauty King.
"He doesn't have any strict England curfews. He will be free on Saturday night to go out for a posh dinner with Mollie and enjoy a few drinks," the source added.
King has also been linked to Prince Harry since splitting with male model David Gandy in February, but she insisted that the pair were just friends.
