“She is the best thing in my life and I am forever grateful I was able to have the time in that relationship for her to come into my life,” Willis concluded.

It’s unclear when the daughter of Demi Moore and Bruce Willis began dating the Vista Kicks frontman, but she confirmed their romance in November 2022 with PDA-packed images.

They had been rumored to be romantically involved since at least August of that year, as Thomas paid tribute to Rumer on her birthday.
