Congratulations are in order for one-third of Runaway June. The country trio's Hannah Mulholland is officially engaged to longtime boyfriend Ian. The girls shared the excitement on Twitter with two photos of the two lovebirds on the beach on Tuesday (Sept. 19).

"Just 2 crazy kids who decided they're gonna marry each other," Hannah writes on Twitter alongside two beach photos.

A rep for the band confirms to Taste of Country that Ian popped the question while the couple were in California, saying: “Runaway June's Hannah Mulholland became engaged to longtime boyfriend Ian in their home state of California over the weekend."

"They are excited for the future.”

The '90s Have Never Sounded So Good!

Mulholland has had an exciting year with the success of the band's debut single, "Lipstick." The follow-up single, "Wild West," further exemplifies the trio's ability for making powerful love songs their own with striking harmonies and traditional country instrumentation.

Runaway June are counting their blessings this year for new engagements and exciting tour opportunities. They have opened for stars like Willie Nelson and Garth Brooks recently and will be touring with Jon Pardi this fall with his Lucky Tonight Tour. Pardi asked the trio to join him on the road in June during a hilarious FaceTime video between them and Midland.

Earlier this year, the group were also selected for Taste of Country's first-ever RISERS class — an elite group of promising up-and-coming country artists to keep an eye on.
