On March 19, 2010, Heidi Montag appeared on The Tonight Show with Jay Leno wearing a dress she claimed to have designed. However, on October 15, 2009, Halle Berry was wearing a dress by designer, Kaufman Franco, that looked nearly identical.
Absolutely.
No, her dress is different.
UPDATE: OMG I just got 2 votes that the dress is different. Wow, I never thought that Heidi and Spencer would both visit my blog, and on the same day!
