Baskett, 32, a former NFL player allegedly cheated on Wilkinson with transsexual model Ava London, reported Us Magazine.
The 30-year-old former Playboy playmate took to Instagram to silence the haters.
"This is the love of my life... A true man. I believe in forgiveness and I believe in him. I take my vows very serious and won't let people's beliefs get in my way of what I know," Wilkinson captioned the picture of the couple.
"Everyone that truly knows @hank_baskett knows the truth and everyone who doesn't creates their own ideas and that's ok but don mess with me and what I love and stand for," she added.
