May 23 (UPI) -- Ramona Singer is taking responsibility after feuding with Dorinda Medley over seating at a charity event.
The 62-year-old television personality spoke out during Wednesday's episode of Watch What Happens Live after Medley, her Real Housewives of New York co-star, accused her of lying about the 2018 Angel Ball.
"It's fine. At the Angel Ball, I really perceived it was a different table," Singer said. "Now I know never to swear on my daughter's life because I may look ageless but my mind isn't. I didn't get it right."
"I messed up," she added.
Singer had invited Medley to the Angel Ball in October but ended up at a different table. The pair clashed about the mix-up during an April episode of Real Housewives of New York.
"You need to say you're sorry that you ditched me for a better table when you told me we were going together," Medley said on the show.
Singer blamed the event organizers in an interview with Page Six in October.
"I was very happy to support the Angel Ball and I thought Dorinda was sitting with me," she said. "She was upset. I had no control of it and I said I was sorry."
On Watch What Happens Live, Singer also addressed Medley's issue with her showing up late to Luann DeLesseps' home during this week's episode. Singer had a birthday celebration with friends the night before but didn't invite any of her co-stars.
"When it came to the birthday party, I have a lot of different girlfriends. It was something separate from the other girlfriends -- I had, like, five different birthday parties," the star explained.
"It is what it is. Sorry," she said.
