Demi Lovato's mess has been quietly mopped up.
"Any and all issues or dispute with Demi Lovato have been resolved amicably and completely," Welch's attorney tells E! News.
Lovato's rep has not yet responded to a request for comment. A spokesman had previously confirmed that the two sides were working on settling the issue out of court.
Welch's lawyer had threatened a lawsuit against the Sonny With a Chance star, saying that his client was left with a black eye, suffered emotionally after the altercation and consulted a plastic surgeon with regard to the physical injury she sustained.
The claws have apparently since been retracted.
Lovato, who is on leave from Sonny while she focuses from getting better, was on the mend in a treatment center in Chicago.
