The two celebrated the holiday with Cyrus' family in Tennessee, including dad Billy Ray Cyrus, mom Tish Cyrus, sisters Brandi and Noah, and brothers Braison and Trace.
Cyrus shared a series of photos of the whole gang on Instagram, writing, "Happy Holidays from America’s most dysfunctional family.”
She also posted a family photo including Simpson on her Instagram Story, as well as other snaps of just the two of them.
On his own Instagram Story, Simpson shared the gift he got for Cyrus: a gold skull necklace. “Museum quality for my queen,” he wrote.
Last weekend, there was speculation that the couple may have split, after Simpson was spotted in NYC with Playboy model Jordy Murray. His agent confirmed to "Entertainment Tonight" that the pair was still together, saying, “There is absolutely no truth to this story. Cody went out with a friend and all the rest is fabricated. Period."
Meanwhile on Christmas Eve, Cyrus reached a divorce settlement with Liam Hemsworth. The two married on Dec. 23, 2018, after years of on-again, off-again romance, but they announced their split in August.
