Tinsley Mortimer feels 'shocked' and 'embarrassed' after skinny dip with RHONY ...

The Real Housewives Of New York looked back at their wild trip to The Hamptons in a new teaser for the second part of their season 12 reunion.

Tinsley Mortimer admitted she was 'shocked' by her behavior during the debauchery-filled trip during an exclusive preview for DailyMail.com, telling Andy Cohen she was a bit 'embarrassed' by her skinny-dipping escapades.

The Bravo host told Tinsley, 45, he was 'impressed' that fellow Housewife Leah McSweeney, 38, was able to convince her to strip down and hop in the pool.

'I was shocked too,' Mortimer said. 'Trust me. I was like, "What if my mom sees me?"'

'I'm such a great influence,' Leah said, adding that she's sure Tinsley's mom Dale Mercer 'really appreciates it.'

Mortimer went on to reveal that she was less worried about stripping down and more concerned with her plain underthings.

'I was embarrassed because I was like, "My God. If I'm going to strip down I might as well have on a cute bra and underwear on," and I had tan colored underwear.'

Leah reassured her she looked good while Mortimer admitted she was happy with her figure.

'I was so much thinner than I am now,' Tinsley said. 'I'll take that body now.'

'Yeah, and I wasn't and they still talked me into in, Sonja added.
