After his VERY awkward entrance - possibly one of telly's cringiest ever moments - Gary inisted he had no idea who French was.
It was despite her insistence that he did know her.
Well it turns out, he does.
In fact, far from just knowing French, Gary and her dated for some two years between 2008 and 2010 after meeting on two separate VH1 shows: Gary appeared on Celebrity Rehab while French was on Rock Of Love 2.
The couple were pictured in LA holding hands and going on dates, the Daily Star newspaper reports this evening.
But despite being an item for all those months, 70-year-old Gary insisted that he didn't have any idea who Frenchy was in the house last night.
Or maybe he's just trying to forget...
CBB airs tonight on Channel 5 from 10PM.
