Black Eyed Peas star Will is said to have been seeing model Casey Batchelor for months after the pair met during filming for The Voice last autumn.
Lads mag regular Casey, who entered the CBB house at the start of the month, joined Will on his tour both here in the UK and on dates in the US.
"They were dating for six months and actually never officially called time on the relationship," a source claimed today. “Will met Casey in a nightclub and they had a series of intimate dates at London nightspots."
Speaking to The Sun on Sunday newspaper, the insider went on to suggest: “She has been very careful not to namedrop Will in the BB house because she is aware of how much he doesn’t like to talk about his love life.
“She’s also hoping they can pick up where they left off."
The supposed source added to the tabloid: "Will is keen to see her again too, so there’s a chance they could rekindle things when she’s done on CBB.”
Viewers of this year's Celeb Big Brother will surely be rather surprised about the news given Casey's rather eagerness to get with Lee Ryan in the house.
The topless glamour model has been caught in a love triangle with Lee and recently evicted Jasmine Waltz almost since Day 1, kissing the Blue singer when the pair were alone in a secret room last week.
