NBA is investigating allegations that Oklahoma City Thunder's Josh Giddey had an inappropriate relationship with a minor after pictures of them - including one where she boasted about having sex with him - were posted on social media

The NBA is looking into allegations that Oklahoma City Thunder's rising star Josh Giddey had an inappropriate relationship with a minor.

Pictures and videos of Giddey with a girl - including one where she boasted about having sex with him - were posted on social media in recent days.

NBA spokesman Mike Bass said: 'The NBA is looking into the allegations of Oklahoma City's Josh Giddey having inappropriate relationship with a minor that have emerged via social media.'

Giddey, 21, was selected by the Thunder with the sixth overall pick in the 2021 NBA draft and he has emerged as one of their key players. 

In one of the images posted online, the girl is seen to be bragging about having sex with Giddey.

The picture - in which a shirtless Giddey is stood behind her - is captioned 'just f***ed josh giddey'. 

Another shows the Australian player with his arm around her body and is captioned 'he says hey'.

There is also a video of Giddey supposedly talking to the girl's brother, in which he says: 'I'm here with your beautiful sister. 

'Good luck for your season. I hear you're going to Sacramento soon for a game so best of luck. We're going to come up and watch you take care of business.'

In another video, where she appears to be stood in the background outside a nightclub, Giddey says: 'What's up my man? We're at the front of the club, me and my girl, about to head back to mine.'

It remains unclear both when and where the pictures and videos were taken and how old the girl actually is.

When asked about the speculation in Friday's practice, Giddey said: 'I understand the question obviously, but there's no further comment right now.'

When pressed for a proper response, he added: 'I get the question guys, I completely understand you guys want to know about it but just for right now, I don't have anything to say.'

Thunder head coach Mark Daigneault also declined to give a definitive answer.

'Personal matter and I have no comment on it,' he said. 'And that'll be my answer on anything related.'

The age of consent in Oklahoma is 16-years-old.

Giddey has been making a name for himself in the NBA since his debut season with the Thunder. 

This year he boasts an average of 12.3 points, 5.7 rebounds, and 4.5 assists.
