Lee entered the Celebrity Big Brother house last Friday (3 January) and has already found himself embroiled in a dramatic love triangle with fellow contestants Jasmine Waltz and Casey Batchelor.
Although he has insisted that he and Casey are just friends and that he is more attracted to Jasmine, Lee appeared to giving Casey mixed signals on last night's episode of the show (7 January) by cuddling and kissing her and even discussing whether they have a future together.
But while Casey tried to work out how she felt, Lee then went and had a cheeky snog with Jasmine!
Nevertheless, Duncan doesn't think there is anything wrong with his best pal's indecisiveness, as he is merely enjoying his single status.
Taking to Twitter this afternoon (8 January), Duncan jumped to Lee's defence by writing: "Think people need to stop giving #leeryan a hard time! He's single, having fun and enjoying his Big Bro experience to the max it seems!"
And it sounds like Blue's Simon Webbe agrees.
Earlier this week, Simon also spoke out about his bandmate's participation in the Channel 5 show and claimed that Lee was just playing along with the game.
He tweeted: "For those who don't get him, give him time. Remember it's a tv show and @LeeRyanMusic is there to entertain you. Whatever you're feeling, you are meant to lol."
He added: "Understand this, @LeeRyanMusic will be himself and you gotta love him for that lol."
Could Lee's way with the ladies of the house be a tactic to win or is he being genuine?
Watch more drama unfold on tonight's episode of Celebrity Big Brother at 9pm on Channel 5.
