Miranda Lambert was a big winner at the 46th Annual Academy of Country Music Awards (ACM) last night (03.04.11).

The 27-year-old singer received awards for best female vocalist and record of the year, as well as video of the year and song of the year for her hit 'The House That Built Me'.

Meanwhile, trio Lady Antebellum scored honours for album of the year and top vocal group, as blonde beauty Taylor Swift took home the gong for entertainer of the year.

After her win Taylor said: "I'm just losing my mind. The fact that this is from the fans makes it so beautiful."

The event, which took place in the MGM Grand in Las Vegas, drew in a number of A-list celebrity guests including Robert Pattinson, Reese Witherspoon, Chace Crawford and Celine Dion and was hosted by Reba McEntire and Blake Shelton, who is engaged to Miranda.

Reba joked about Taylor's tendency to write songs about her ex-boyfriends, quipping: "If you make her mad, she'll write a song about you."
