In June, former X Factor judge Tulisa appeared in court accused of setting up a drugs deal, however she walked free after the trial collpased.
The N-Dubz star will now make a brief return to The X Factor this weekend, when she joins Louis at Judges' Houses. She has spoken about how grateful she is that he and Simon have supported her.
In an interview with the Sunday Mirror, Tulisa said: "Louis was one of the people that stuck by me all the way. He's a true friend. He openly supported me, not caring at the time what people thought.
"I'd really like to thank the whole of X Factor, including Simon Cowell, for being so supportive of me."
The singer added that some of her personal friends deserted her during her time of need, unlike Louis and Simon.
Ahead of this weekend's Judges' Houses, Tulisa has shared a snap of herself and Louis standing by the pool together in Bermuda.
Louis was said to have "really petitioned hard" for her to make a comeback, while Simon said it was "fantastic" to see Tulisa return to the ITV1 reality show.
Last night (28 September), Louis was seen selecting his final six groups, which joined him and Tulisa in Bermuda for the last stage of the competition before the lives shows.
The pair whittled the hopeful singers down to just three bands, but we'll have to wait and see who makes the cut!
Those in the running are: Only The Young, Concept, The Brooks Twins, Blonde Electric and a new girl band and new boy band who are yet to be named.
