After filing for divorce from husband Jason Hoppy a few days earlier, the Skinnygirl mogul took her beloved dog, Cookie, for a walk in New York's Tribeca neighborhood on Sunday.
Bundled up in a down jacket and boots, Frankel, 42, shielded her face with sunglasses as she strolled down the street with her pup trailing behind her.
Frankel first announced the couple's separation via a statement on Dec. 23. "It brings me great sadness to say that Jason and I are separating. This was an extremely difficult decision that as a woman and a mother, I have to accept as the best choice for our family," she said at the time.
The couple – who married after a whirlwind courtship and surprise pregnancy in 2010 – are parents to Bryn, 2½.
While Frankel and Hoppy's relationship played out in front of the cameras on Bethenny Getting Married and Bethenny Ever After, last year Frankel took time off from her life in the spotlight to focus on her marriage.
"Bethenny is devastated," a friend of Frankel's told PEOPLE earlier this month.
