When you're the Queen of Country Music, you get invited to some of the biggest Hollywood parties. Reba McEntire spent her weekend partying with Jennifer Lopez for the singer's 47th birthday in Sin City.

J.Lo invited some of the biggest stars out to celebrate her 47th and that included country stars McEntire and Brooks and Dunn, who are no strangers to Las Vegas. The three country icons were already in Vegas for their residency with shows running through the end of July.  With them already being in town, it was a no-brainer when they got an invite to the big birthday bash.

McEntire dressed up for the occasion in all black with a sparkly silver scarf around her neck. Ronnie Dunn also went for black on black on black -- looking handsome in a black jacket and dress shirt. Kix Brooks kept it a little more casual for the event, wearing khakis, a dress shirt and a leather jacket.

Before the party, Lopez performed her own show in Vegas before inviting all her celeb guests to help her celebrate. Kim Kardashian West, Kanye West and Taylor Swift's recent ex-boyfriend, DJ Calvin Harris. Recently there's been a ton of drama surrounding Swift and Kimye and, judging by his attendance at the party, Harris has picked a side. According to People, he was friendly with Kardashian West.

Despite the social media drama, the evening looked drama-free and tons of fun. McEntire looks like she's having a ball in the photo she posted -- hugging her friends close.

You Won't Believe Reba's First Job Ever!
