Kardashian, Austin 'not super serious'

Kim Kardashian is reportedly not in a serious relationship with her Dallas Cowboys boyfriend Miles Austin.

According to E! Online, the Keeping Up With The Kardashians star is enjoying her time with Austin but is not ready to settle down.

"[They're] having fun this summer [but] things are not super serious," said an insider, who also claimed that Kardashian is not planning to attend the team's first game of the season.

"They're taking things slowly [and] are cooling off a little," added the source. "Kim wants to be single and date around."

Kardashian - who previously dated Reggie Bush - and Austin are thought to have begun dating earlier this year and the reality star was recently spotted sitting on the sidelines while the footballer trained with the Cowboys in Texas.

She has remained coy on their relationship and recently told Ryan Seacrest's radio show that she is "single" and "having a good time", adding: "I'm meeting some really great people and just trying to live my life and definitely be a lot more private than I was before."
