The 23-year-old beauty hooked up with the 30-year-old Premier League striker shortly before she entered the Big Brother house when they were both single.
Friends reveal that the Spurs footballer, who is in England’s squad for tonight’s friendly against Scotland, made a series of visits to Gina’s home in north London.
They revealed he would arrive under cover of darkness in luxury cars, including an Aston Martin, and spend several hours with wealthy Gina, who receives a £10,000-a-month allowance from her mum.
The smitten babe, who is one of the favourites to win Big Brother next week, was said to be “flattered” by the hunk’s secret attentions.
But she has been agonising over whether they would become an official item and go public with their romance.
Babe magnet Jermain has dated a string of celebrity babes, including model Danielle O’Hara, 29, The X Factor’s Alexandra Burke, 24, and Celebrity Big Brother champion Chantelle Houghton, 29.
“Gina met him on a night in London and secretly exchanged phone numbers. She was so excited when he made contact.
“Gina is pretty smitten but realises he is a bit of a bad boy. However, it is clear he likes her and she hopes her stint in Big Brother might make him even keener.”
A spokesman for Jermain, who confirmed the player is currently single, said: “I cannot imagine this is something he would wish to comment on.”
