Sackett shared that she found out Kinney was cheating on her with Lady Gaga when the actor accidentally dialed her in the middle of the night.
She expressed hope, however, that Kinney did not do the same to the "Bad Romance" singer.
Back then, she told her Instagram followers, "Taylor and I have always believed we are soulmates.
Just like all couples we have ups and downs, and we have been taking a break. We just love with everything we have.” She continued, "And sometimes I don't know that that love is met with the type of dignity that we wish it would be met with.
“So proud to have been the 1st Woman to headline at Wrigley Field #joanneworldtour,” Gaga captioned the below photo on Twitter.
