Miranda Lambert has bought Carrie Underwood a motorbike.

The country singers recently collaborated on a duet of 'Something Bad' on the Billboard Music Awards and as a thank you, Lambert bought Underwood a new bike.

Next to her on a picture of herself new hefty black two-wheeler, Underwood wrote on Twitter: "Well, it's not every day @mirandalambert buys you a motorcycle! Next stop, motorcycle driving lessons!!! #RansTheBest"

Underwood will have plenty of space to ride her new bike, as she and husband, Mike Fisher, bought 400 acres of land near Nashville, Tenn., in 2011 on which they have built their dream home.

The blond beauty -- who was catapulted into the spotlight after winning 'American Idol' in 2005 -- has also been working on her fifth album, and has been writing her own tracks for it.

She recently said: "I've been writing quite a bit, it's exciting! It definitely has a different sound. There are some thematic things that are quite different. I love strong women. So I want things that I can get on stage and just feel empowered."
