Responding to critics who said she profited
off of her 72-day marriage to Kris Humphries, Kim Kardashian
quipped Monday that filing for divorce
from the New Jersey Nets star was "a bad business decision."
"If you really think about it, if [the marriage] was a business decision, and I really made all that money that everyone was claiming that we made off this wedding, and if the wedding was fake and just for TV … I'm a smart business woman. I would have stayed married longer," Kardashian said sarcastically, while appearing as Kelly Ripa
's co-host on Live! With Kelly
Monday morning. "This was a bad business decision. If you really think about it, it doesn't make sense."
Kardashian, 31, told Ripa, she fled to her mother's house
with two pairs of sweatpants and a pair of pajamas immediately after filing for divorce. Since then, she said, she's been splitting her time between her mom's and her sister Kourtney
"I really did some soul-searching, and I needed that," she said. "I needed to just be with the family."
The socialite and reality TV star
, who called herself as a "hopeless romantic," told Ripa she was surprised by the vitriol her divorce inspired
"It's been a hard couple of months," Kardashian admitted. "I really didn't think that following my heart would create this much backlash."
