Trisha Yearwood celebrated her 51st birthday in style on Monday (Sept. 21) with a private gathering at Six Flags Over Texas.

Yearwood turned 51 on Saturday (Sept. 19), but she was in the middle of a multi-night concert engagement at American Airlines Center in Dallas with her husband, Garth Brooks, as part of their ongoing world tour. According to NBC Dallas-Ft. Worth, the amusement park is only open on weekends, but made arrangements to accommodate Brooks, Yearwood and their band for the outing, which was a surprise to Yearwood.

Brooks says his favorite ride was Mr. Freeze, while Yearwood prefers the Texas Giant. Scroll through the gallery above to get in on the fun.

The couple kicked off their current tour last year, marking Brooks’ first full-fledged tour since he took a long hiatus to raise his daughters, and it’s been so successful that Brooks was recently named the highest-paid country entertainer of the past year, raking in an incredible $90 million over the last 12 months.

Brooks released his most recent album, Man Against Machine, last November, and is featuring new music in his shows. Yearwood is also performing her own greatest hits, along with selections from her most recent studio collection, PrizeFighter: Hit After Hit.

The Dallas shows, which wrapped on Tuesday night (Sept. 22), were the first after a break in the tour, and the couple changed up the staging for the new leg.

“We’ve been out on the road for 10 months,” Brooks tells 102.3 BlakeFM. “We have taken a lot of looks at what’s working, gotten rid of the things that weren’t, and we’re coming out with a brand-new look. We’re gonna re-design the whole video world, the wings of the stage are a little different, and the set list is starting to fall into the sweet spot.”

Brooks and Yearwood were also recently inducted into the Music City Walk of Fame in Nashville.
