The One Direction heartthrobs lived up to their cheeky chappy reputations when they appeared on the 55-year-old presenter's ITV talk show today (19.10.15) by flirting with the host.

Niall, 22, said: "I'm just obsessed with you Lorraine, I can't even look at you ... I watch the show every day, it's brilliant."

Clearly disappointed at being left out of the flirtations, Harry, 21, added that he too is a big fan of the show but hasn't had the time to watch it.

Speaking about the sacrifices they make for their music career, Harry teased: "I haven't watched 'Lorraine', my favourite show, in far too long."

However, Niall wasn't happy about his bandmate getting all the attention, adding: "Well I have. I watch it every day."

The 'Drag Me Down' hitmakers - who, along with bandmates Liam Payne and Louise Tomlinson, are set to go on hiatus next year - are now looking forward to spending more time with their family and friends, when they're not busy watching 'Lorraine'.

Niall said: "Probably the only downside to what we do is not being able to see our families as much and our friends as much as we have previously. So that will probably be the first thing that will come to our minds when we start taking a break. Just to go home, see everyone and hang out with people. Sometimes we only get to see our family for two or three days at a time."
