The former Made In Chelsea star sat Sam down and began to show off his sexiest moves, while lifting up his T-shirt to reveal his chest and the waistband of his boxers.
And it looks as though he was getting pretty into it. Oo-err!
As for TOWIE star Sam, we're not sure exactly how much she was loving Ollie's gyrating, since she can be seen giggling at her housemate for most of his routine.
But the Essex babe wasn't the only lady in the house who was given a lap dance, as Ollie also worked his magic on wild party girl and baking entrepreneur Luisa Zissman.
Of course, Luisa wasn't afraid to really embrace the Chelsea star's moves and she couldn't resist rubbing her hands on Ollie's torso at one point.
Although it looks like Ollie was treating almost every housemate to a lap dance, we can imagine that performing for Sam was a little bit more nerve-wracking, since he has admitted to having a big crush on her.
On yesterday's episode of Celebrity Big Brother, Ollie opened up about his feelings for Sam and said: " I had different perceptions of Sam when I came in here and she's proved me in a very different way, in a good way. And the fact that she's not like most reality people that I know."
Meanwhile, the TOWIE regular has revealed that she would in fact like to spend time with Ollie outside of the CBB house.
The potential love birds - as well as Luisa, Dappy, Jim Davidson and Casey Batchelor - will be leaving the house tonight (29 January) on the final episode of the hit Channel 5 show, when the winner will be crowned.
Watch Ollie's lap dance below.
