The singer and "The Young and the Restless" star have been active on one another's social media accounts for two weeks and Lovato even made an accidental cameo in a livestream Ehrich posted on Saturday (28Mar20) to entertain fans.
Two days later, Ehrich shared a shot of himself cuddling up with the "Cool for the Summer" hitmaker's beloved dog, prompting Demi to make it clear how she feels about her new man - and her pup.
"My angels," she commented under the shot.
Ehrich also chimed in on one of Lovato's posts, referring to her as a "Literal angle" after she announced that some proceeds from her upcoming Fabletics line will benefit the COVID-19 Solidarity Response Fund for the World Health Organization, powered by the United Nations Foundation.
Demi plans to donate $5 (£4) of every item sold up to $125,000 (£100) to will go to the charity.
The capsule collection will be available from Thursday (02Apr20).
