It's business as usual for Bethenny Frankel
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.
