One Direction's Niall Horan and X Factor star Alexandra Burke have been BFFs for AGES.
Niall, who is feeling pretty poorly after just finishing his One Direction Australia and New Zealand tour with bandmates Harry Styles, Louis Tomlinson, Liam Payne and Zayn Malik, dared to go into innuendo territory with his latest tweet to Alex.
Niall Horan tweeted: "@alexandramusic ari alex..whats crackin? since im gona be soo tired n jetlagged when im home..ur gona havta help me out hahahaha. i joke xxx"
Errr help me out, we're not EXACTLY sure what that means Nial *sniggers*.
But soon enough trusty Directioners helped us out. @_LoveForHoran_ posted: "@NiallOfficial @alexandramusic in there!"
And @lovenutton added: "@NiallOfficial YOU SAID I WAS THE ONLY ONE"

Alexandra recently confessed that One Direction's Niall is one of her besties, telling The Mirror they chat every single day.
She said: "I speak to Niall every single day, he's such a sweet boy.
"We've been friends for ages — he's the one in the group I really talk to, the one I really know the best."
But the singer has got eyes romantically for someone else - stepping out arm-in-arm with new boyfriend Jermain Defoe for the first time today, confirming their relationship.
The pair, who have been rumoured to be dating since last month, looked loved-up as they strolled together out and about in Hertfordshire yesterday.
