So you know Taylor Swift has had a HUGE pop hit with "I Knew You Were Trouble," which has now held the top spot on the pop-oriented Billboard Mainstream Top 40 chart for six weeks.

Oh, but that's not all. Taylor is also currently on top of the Country Aircheck/Mediabase chart with another song, "Begin Again."

Fans are undoubtedly getting excited, because Taylor begins touring again March 13 in Omaha, Neb. Her camp announced Wednesday (Feb. 27) that Florida Georgia Line ("Cruise") and Casey James ("Crying on a Suitcase") will each open some dates along with British singer/songwriter Ed Sheeran, who will be supporting all of Taylor's shows.

Another question worth pondering: Will Taylor have all those pop, country and rock star surprise guests that she did during her last tour?
