They’ve been linked romantically in recent weeks.

And, while many struggled to believe in a relationship between Justin Bieber and Kourtney Kardashian, the pop star has now spoken out about their alleged union.

In an interview with radio show The Bert Show – which was recorded on December 17 but is set to air on Wednesday – the 21-year-old star is heard saying that he is being ‘used’ by the 36-year-old.

‘I’m being used!’ Justin Bieber said in a radio interview on The Bert Show that he is ‘being used’ by Kourtney Kardashian, as a response to relentless romance rumours

Rumours have been swirling about the couple since early October, and have refused to die down as they continue to play coy.

But, in the recent interview, the Sorry hitmaker – when asked about his ‘fling’ with Kourtney – replied: ‘I’m being used, man. What can I say?’

When the host Bert Weiss continued, asking if there is ‘Anything there?’, the young singer replied: ‘Nah, we’ll leave it at that.’

After a brief pause, he added that he has only love for the Keeping Up With The Kardashians star and mother-of-three, who split from her long-term boyfriend Scott Disick last summer. 

It's got to sting: The next day Justin Bieber, 21, would admit that he was 'used' by Scott's ex Kourtney Kardashian, 36, during a teaser for The Bert Show , which was was recorded on December 17 but is set to air on Wednesday. In December UsWeekly broke the news that Kourtney and Justin dated from August until October; here they are seen in October

What’s going on? The pair – who are 15 years apart in age – have been linked since December, but it’s thought they had been dating for two months by that time

‘No, no, but for real, she’s great. I’ve known [the family] for years,’ he continued, seemingly brushing it aside.

The notion of a romance between the singer and the reality TV star, who are 15 years apart in age, first arose in early December when the two were spotted hanging out together at the Nice Guy in West Hollywood.

The pair were said to be very ‘touchy feeling’, before Kourtney was then pictured leaving a Beverly Hills hotel often frequented by Justin. 

‘Justin and Kourtney have been hooking up since late August, early September,’ a source told Us Weekly  at the time.

Previous reports said the duo first hooked up in October after they were seen hanging out at Universal Studios’ Halloween Horror Nights.

The pair appeared in an Instagram picture wearing 3-D glasses in December and were said to have spent time together later that night. 

And, as the claims emerged, Justin added fuel to the fire by posting a picture on Instagram of himself in front of a leggy woman seated on the hood of a car.

The Canadian superstar captioned the seductive shot ‘Lord knows…’, which many assumed was a quip at Kourtney’s ex-beau Scott, who calls himself The Lord.

But it was later revealed that it wasn’t Kourtney in the picture, rather a gorgeous mystery blonde woman.

‘Oh yeah, that’s definitely happening and has been for some time now,’ a different insider told Us.
