Miranda Lambert, sporting a Barbie doll-pink mini-dress, accepted the award for Single Record of the Year for her song 'The House That Built Me' at tonight's ACMs.

'Entertainment Tonight' special correspondent Nancy O'Dell presented the award to the 'White Liar' hitmaker, who used her short acceptance speech to thank -- and congratulate -- songwriters Tom Douglas and Allen Shamblin, who penned the hit.

"Thank you so much. I love 'The House That Built Me,'" Lambert said modestly, before thanking her record producer.

'The House That Built Me' is the third single from Lambert's third studio album, 'Revolution.' The singer is also lined up to possibly pocket the coveted Entertainer of the Year award tonight.
