It's official: [artist id="2389485"]Taylor Swift[/artist] is now famous enough to headline a tour. The country singer, whose album [article id="1603490"]Fearless is once again #1[/article] on the charts (that's eight weeks for those keeping count), is riding high on the success she's had over the last year. And, although she's opened for acts like Tim McGraw, Faith Hill and Rascal Flatts in the past, she's excited to finally get the chance to have her own opening act -- who just happens to be one of her best friends.

"My headlining tour starts in April, so I'm really excited about that. For the past three years I've been writing down ideas for ... a headlining tour, and I get to do one now," the singer told MTV News. "It is unbelievable to me that that is actually happening. But I'm planning the stage and the wheels are all turning."

She also shared why she has another reason to be excited for her tour -- she's taking a good friend and "American Idol" alum with her. "[artist id="2385935"]Kellie Pickler[/artist] is actually going to be my opening act ... she's, like, my best friend. It's going to be really fun just spending the summer with your best friend. [It] solves that issue of ever being bored!"

In addition to her spring tour, Swift will be busy with appearances on both the small and big screens. In February, when "Jonas Brothers: The 3D Concert Experience" hits theaters, fans will get to see Swift as she makes a cameo in the film. "We always have been friends with Taylor. She's a great girl, and she's an incredible musician," Kevin Jonas recently said. "One of the coolest things is that [article id="1603470"]Taylor, she's in ['Jonas Brothers: The 3-D Concert Experience'][/article]. We performed along with her, and it's great. It's a lot of fun."

Also, in March comes her [article id="1603548"] "life-changing" "CSI" cameo[/article]. "Basically, when I'm really old and can only remember one story about my life to go back and relive, and tell over and over and over again to the point where my grandchildren roll their eyes and leave the room, that's the story," she blogged about the experience. "Ah, I can see it now. 'You know, when I was a youngster, I got to guest star on "CSI"! It was marvelous! So marvelous, it was!' "
