Leave it to country cutie RaeLynn to celebrate her engagement in adorable style! The singer celebrated her upcoming nuptials with a Christmas-themed party that was hosted, partially, by her "The Voice" mentor Blake Shelton.

RaeLynn got engaged to Josh Davis in mid-October and it wasn’t long before she gushed about Shelton’s involvement in the engagement — saying he’d be throwing them a shindig to celebrate! Shelton co-hosted it along with Amanda Craig, an important member of RaeLynn’s glam squad.

Shelton didn’t attend the party solo. Despite his relatively recent divorce from Miranda Lambert,he brought along his new girlfriend and fellow "The Voice" coach, Gwen Stefani. The two got in on the ugly sweater theme by dressing up and taking lots of silly photo booth photos with RaeLynn, her fiance and other attendees.

Shelton and Stefani confirmed they were an item early last month and have been very public since. The two were spotted together following November’s CMA Awards and there have been a ton of paparazzi photos. These pics may be the cutest yet.

RaeLynn didn’t seem to mind having Shelton’s new main squeeze at her party, she’s smiling big in all the photos and acting silly next to the pop singer. Lambert was not in attendance, but we bet the singer will have a celebration of her own for her friend RaeLynn.

RaeLynn and Josh Davis are set to get married on Feb. 27, 2016.
