Simpson took to Instagram Stories to celebrate their relationship milestone with a silly photo of Cyrus wearing spot cream on her face.

“6 months with you is worth a lifetime with anybody else,” the 23-year-old “Prince Neptune” poet wrote of Cyrus, 27, adding, “I love you.”

They two have been linked as a couple since October 2019 when they were seen locking lips in LA.

Since then, Simpson and Cyrus haven’t been shy about flaunting their relationship on social media and have even gone so far as to get several matching tattoos.

The pair has also spent big holidays together including Thanksgiving, Christmas, and Halloween. And, last week, things appeared to get more serious for the couple as they adopted a dog together. 

Cyrus was previously married to Liam Hemsworth, though the couple was together for less than a year and separated in August 2019.

She then had a brief PDA-filled fling with Kaitlynn Carter before they broke things off and Cyrus dove into her relationship with Simpson. Meanwhile, Simpson’s past pairings include supermodel Gigi Hadid.
