This week, while Blake Shelton holds up camp at No. 1 on Billboard's country singles chart, Taylor Swift takes up residency at the top of the Mediabase/Country Aircheck country singles chart with her latest hit, 'Mean.'

By topping the charts this week, Swift scores her eighth No. 1 single to date and her third consecutive chart-topper from her latest triple-platinum album, 'Speak Now.'

Besides taking over the No. 1 slot on Mediabase/Country Aircheck charts, Swift's video for 'Mean' also holds the top position on both CMT (two weeks) and GAC (three weeks).

Over the weekend, the young superstar took the stage at Gillette Stadium (just outside of Boston) where she performed to over 110,000 fans with back-to-back sold-out shows. The shows were part of her 2011 Speak Now World Tour, which kicked off last month, and you can see exclusive pictures here.

During Saturday's performance (June 25), the night skies opened and Swift played the second half of her show in the pouring down rain, soaking wet. Midway through 'You Belong With Me,' the light rain became a downpour, but Swift continued on with the show, singing to the outdoor crowd of 55,000 fans who were drenched and enjoying every second of the memorable performance. Swift is the first and only female artist to ever sell out Gillette Stadium in its history of live performances.

Swift continues on this week with her Speak Now Tour, stopping in North Carolina, Tennessee and Kentucky. For a complete list of dates where the tour will be, click here.
