LAS VEGAS — Country icons Reba McEntire and Brooks & Dunn are joining forces to become the newest headliners on the Las Vegas Strip.

"Cake and ice cream are good, but when you put 'em together, it's even better," McEntire said at a news conference announcing the trio's residency at the Colosseum at Caesars Palace starting June 24.

The three bantered like the "best friends" McEntire said they were, describing a dinner about six months ago when the idea cropped up and Ronnie Dunn said, "heck, let's do it."

Their people talked with Caesars and co-producer AEG Live, and the plan was worked out in the last two months.

"It's magic," Reba said of how their on-stage reunion in the 4,000-seat venue came about.

The show, "Together in Vegas," includes 12 performances in June, July and December 2015.

Tickets start at $59.50 and will go on sale Dec. 4.

For McEntire, Vegas is one of the places she got her start. She opened for country legend Roy Clark in the 1980s at Caesars Palace and lost her voice after performing two shows a night for six nights.

Kix Brooks said he and Ronnie Dunn would often end tours in Vegas.

McEntire is a two-time Grammy winner with 35 No. 1 hits and a litany of country music awards to her name. She has since branched out into TV, starring in the sitcom "Reba" and "Malibu Country."

She's recording new songs, too, a first in more than five years.

Brooks & Dunn performed together for 20 years, releasing their first album in 1991, before pursuing solo careers most recently. Known for hits including "Boot Scootin' Boogie," "Only in America," and "My Maria," the duo has also won two Grammy awards and dozens of country music honors.

McEntire has toured with the country duo before, and the trio tougher recorded "Cowgirls Don't Cry."

"The hijinks are unnamable," McEntire said of their tours in the 1990s.

The trio revealed little about their production's plans, including an as-yet-undecided set-list, except to say it would be filled with each of their greatest hits.

"Nothing in cement, yet," McEntire said.

"He's going to be the flash and sparkle," she joked of Dunn.

The announcement comes as the National Finals Rodeo returns to Las Vegas this week and the area becomes a destination for country fans.

The Colosseum is home to another country music powerhouse, Shania Twain, until mid-December. Other rotating headliners at the Colosseum include Rod Stewart, Elton John and Celine Dion.

Dion, though, announced in August that she needed to cancel all shows scheduled through March to focus on her health, her husband's recovery from a cancerous tumor, and raising her three children.
