And we pretend to be his girlfriend. Funny that.
There are a lot of things we'd do if we were friends with Niall Horan. Ruffling his blonde hair, eating loads of Nando's together and trying to make him fall in love with us are just a few examples.
Tulisa, however, has admitted that one of her favourite things to do with her blond-haired pal is pretend to be his sister.
Speaking to I Love Pop Magazine about hanging out with Goldilocks at V Festival, Tulisa said: "We had such a good time. We were dressed in our hoodies and sunglasses, walking around the crowd.
"And because we were both blonde and the same height we pretended to be brother and sister.
"The second people walk past and say, 'Is that...?' We'd start being really loud, shouting at each other in northern accents like, 'What have you done with me ciggies?' or 'Pass us that bloody pint, if our mother was here now she'd blooming kill us! Aahh, come on Chez!'"
Ok, we want to play this game. It sounds hilarious.
"Tom and Chez are our nicknames when we get together," continued Tulisa. "People look at us like, 'Oh no, that can't be them...' because we're talking in these really loud northern accents.
"Now I've given it away! We'll have to change it. Now we'll pretend to be from Liverpool."
Be warned - if you look ANYTHING at all like Niall Horan and you have a northern accent, 'enthusiastic' One Direction fans are NOT going to believe you when you say you're not the 1D hearththrob.
Then again, you look like Niall Horan - so we're not going to feel sorry for you.
Whaddya reckon scapers - did Tulisa and Niall's game make you laugh? DID ANYONE SPOT 'CHEZ' AND 'TOM' AT V FESTIVAL?
