Washington, Nov 25 : American country pop singer Taylor Swift threw a surprise 16th birthday party for Hannah Montana star Miley Cyrus at the American Music Awards.

Swift, who is Cyrus''s BFF, arranged the birthday bash backstage, complete with balloons and a cake.

“Us girls (including Julianne Hough, Jordin Sparks and Ashley Tisdale) got together and thought it would be fun to do a little surprise party for Miley, she deserves it,” Fox News quoted Swift as saying.

And for her birthday party, Cyrus got really cool gifts, especially from her parents.

“I bought Miley her very own recording studio,” Billy-Ray Cyrus said proudly.

Last month Cyrus''s employers, Disneyland, had closed down the entire park for the first time in history so that she could celebrate her sweet 16 birthday with 500 frenzied fans. (ANI)
