Paul Wharton, Dan Gasby, Alex Lerner

ABC7 anchorman Paul Wharton spilled tea about his close friend, restaurateur B. Smith and her husband, Dan Gasby, on ABC’s Good Morning Washington on Wednesday.

Gasby is catching heat on social media for moving his mistress, Alex Lerner, into their home after Smith was diagnosed with Alzheimer’s disease in 2014.

Wharton, who has known Smith for many years, shared exclusive video he recorded at a pool party in the Hamptons last year.

The video shows Gasby and Lerner making out in the pool in the background. Wharton says he was unaware Gasby and Lerner were a romantic couple.

“I’m thinking that they just came as friends,” said Wharton, who admits he low key recorded the pair cavorting in the pool without their knowledge.

Wharton said “all bets were off” after Gasby sold his and Smith’s story to PEOPLE magazine.

He described an incident he witnessed in Smith’s home when Lerner “chastised” Smith by smacking her hand.

“And I grabbed Alex’s hand, and I said, ‘Alex, you know you really can’t do that,'” Wharton recalled.

Wharton also said he saw Lerner “slap the heck out of Dan” after he said that Smith was the kindest, sweetest woman he’d ever met.

Wharton quoted Lerner saying, “I’m sitting here, and you’re saying that B is the kindest, sweetest woman you ever met?”

Wharton said he reminded Lerner that Smith is still Gasby’s wife.
