There were rumours about their fling in May this year but this time things are said to be more serious between them.
"Louise has been dating Niall - they've seen each other lots and talk all the time. But it suited both of them for their nights together to be secret. He'll sneak her into his house in North London, often when it's dark," dailymail.co.uk quoted a source as saying.
Thompson, known for starring in reality show "Made In Chelsea", tries to keep her relationship under wraps.
"She makes sure she doesn't do anything around 'Made In Chelsea' to try and keep the romance away from the prying eyes of her co-stars on the show," said a source.
