This week, Keith Urban’s 'Long Hot Summer' has climbed to the top of both the Billboard and Mediabase/Country Aircheck country singles charts, marking the singer's 13th career No. 1 single to date.

Urban co-wrote 'Long Hot Summer' with Richard Marx and recorded it for his 'Get Closer' album, which was released last year. The twosome have a run of luck with writing successful songs, as the two are the same writing team behind Urban's previous hits 'Better Life' and 'Everybody.'

"I love writing with Richard," says Urban in a press statement. "We wrote a bit for the last record and nothing sort of eventuated from it, and it frustrated me. I thought, 'We need to go at it again. I know we can write a song. So he came to Nashville, and we had just under a few hours to try to come up with something, and lo and behold, this song came out of the session."

'Long Hot Summer' was released as the third single from 'Get Closer,' following previous singles 'Put You in a Song,' which peaked at No. 2, and 'Without You,' which topped the charts this past June.

Next week, Urban will be releasing his fourth single from the 'Get Closer' album, 'You Gonna Fly.' Look for Urban to perform the tune today (October 11) on 'The Ellen DeGeneres Show.'

Urban is in the midst of his Get Closer 2011 World Tour, which wraps on October 15 in Minneapolis, Minn. Next month, Urban will appear at the 45th Annual CMA Awards, where he is nominated for both Entertainer and Male Vocalist of the Year. The singer-songwriter will also perform during the awards, which will broadcast live on ABC on Wednesday, November 9 at 8:00PM ET.
