The couple launched their second round of the 10 weekend Soul2Soul show at the Venetian on Oct. 25. Since then, it appears speculation that the two are splitting up as died down.
In the meantime, McGraw's single Southern Girl just topped this week's Mediabase country songs.
During a press conference he said about the respective track, "I think on every record there's a song that the fans take and make their own, and we saw that happen with Southern Girl on the road this summer...I listen to country radio every morning without fail. Even after 35 of these, hearing your local DJ introduce and then play one of your songs will never get old."
He spoke told Radio.com in February that the hit song was one of his favorites on his Two Lanes of Freedom album, adding, "The guitar tones in Southern Girl were something I wanted."
Hill and McGraw, who celebrated their 17th wedding anniversary in October, have remained quiet since the rumors sparked this past April. However, they may have made some sort of statement on the opening night of Soul2Soul (Oct. 25) when they both posted a picture on Instagram walking hand-in-hand.
Hill added the caption "dinner break with band & crew after rehearsals #soul2soul" while McGraw wrote, "Ready for opening night #soul2soul"
There also didn't seem to be any animosity between the two as they made their rounds to promote Soul2Soul. They both said they were excited and happy to be hitting the stage with one another again.
Hill said, "Tim and I love performing together, but it's been such a scheduling challenge last few years because we have two careers and three teenage daughters' school and social calendars to coordinate."
McGraw and Hill did Soul2Soul at the Venetian from October 2012 to April 2013. It was such a success, they were asked to come back for another series. It's set to end on April 12, 2014.
McGraw said, "We had a lot of fun onstage and off stage...The reaction was impossible to ignore, so it was a total no-brainer to add more shows when the Venetian asked us."
