Gospel star Tina Atkins-Campbell has vowed to work through her marriage troubles after separating from her husband last year (13).

The Mary Mary singer was left distraught after discovering her husband Teddy Campbell, a drummer working on U.S. reality show American Idol, had been cheating on her with a friend, and they have been attempting to patch up their relationship ever since.

The drama has been captured on film for the upcoming third season of Atkins-Campbell's U.S. reality show Mary Mary, and she admits working on her love problems on camera has been tough, but the 39 year old is determined to save her 14-year marriage.

She says, "We're working through it... We've gone through all of those stages (of separation)...

"Life happened and if I had known what this season would consist of before I started, I would have opted out..."

The couple has four children together, ranging in age from one to 10, while Teddy also has a 19 year old daughter from a previous relationship.
