Bethenny Frankel and husband of 2 years separating

The 42-year-old TV personality, chef, author and entrepreneur told The Associated Press Sunday that the split brings her "great sadness."

"This was an extremely difficult decision that as a woman and a mother, I have to accept as the best choice for our family," Frankel said. "We have love and respect for one another and will continue to amicably co-parent our daughter who is and will always remain our first priority. This is an immensely painful and heartbreaking time for us."

Frankel and Hoppy were married in 2010 and have a daughter, Bryn, who was born that same year. The couple's courtship and marriage were documented in two reality series, "Bethenny Getting Married?" and "Bethenny Ever After..." Frankel gained fame as a star of "The Real Housewives of New York City." Since her stint on the Bravo show, she has written four books, released a fitness video and founded her Skinnygirl line of cocktails, shapewear and nutritional supplements.

She launched a talk show, "Bethenny," over the summer that is set to air nationally on Fox stations in 2013.
