Sheree's Ex Bob Admits He's Still Close With Rumored Mistress Tammy

Sheree Whitfield battled out her differences with her ex-husband Bob Whitfield's best friend Tammy McCall Browning during a group trip to Miami this season on Real Housewives of Atlanta.

Whitfield questioned if McCall Browning had slept with her ex, but the friend of the Housewives denied any such interaction.

Listen! 'RHOP' star Wendy Osefo breaks down the “most intense fight in the show's history” in under 2 minutes.

Despite the fact that the fight took place months ago, RadarOnline.com has exclusively learned the two women still don't get along.

"Because Tammy is of the era when me and Sheree's relationship became tumultuous, I think Sheree won't let the sleeping dogs lie," Bob, 44, told Radar. "I still feel that it's unresolved maybe?"

Bob now tries to keep his relationship with Sheree separate from his friendship with McCall Browning.

"That's my friend over there," he said. "So I won't commingle."

He's just enjoying both women at the same time.

"For most people, I think that they would have a real enjoyment to have two people to covet," he admitted. "And there's different types of experiences with everybody, so it's not going to be the same conversation between the two people. So I always looked at it like you can have friends and lovers, just don't commingle the two."
