Welcome to RHONY, Tinsley Mortimer!

A source revealed to RadarOnline.com exclusively that Mortimer, 41, is the newest addition to The Real Housewives of New York.

The socialite previously starred on her own reality show — High Society — but it was cancelled after just eight episodes.

Mortimer made headlines again in April when she was arrested for trespassing at the Palm Beach, Fla. home of her boyfriend.

Radar reported that the on-again-off-again couple had a history of physical abuse. It is unknown if Nico Fanjul will make an appearance on the Bravo show.
