Miranda Lambert has announced a new partnership with Ram Trucks, and -- surprise, surprise -- it'll help her fund her passion for animal rescue.

Ram Trucks have donated a customized Ram Laramie Longhorn, which Lambert will auction off to benefit her MuttNation Foundation, a donation-supported 501(c)(3) foundation whose purpose is to better the lives of shelter animals.

The auction kicked off Nov. 5 and runs through Nov. 15 on eBay. In addition to the Ram 1500 Laramie Longhorn, fans can also bid on signed copies of Lambert’s 'Platinum' CD, signed guitars and tickets to one of her concerts in 2015, including a pre-show cocktail with the singer.

The auction is just the beginning of the relationship between Lambert and Ram Trucks, with more news to come in 2015.

“I have lived my entire life surrounded by trucks even to this day. I have also written songs that mention trucks, so I am so happy to be partnering with Ram," Lambert says. "And I'm thankful for their generosity in allowing me to auction off a Ram Laramie Longhorn for MuttNation Foundation. It's a cause so close to my heart! I'm looking forward to more exciting news with Ram Trucks in 2015."
