Mischa Barton may have turned 21 last week (finally, someone will let the girl have a drink), but it wasn't the joyful affair it should have been. Rumor has it that Mischa's big night was marred by the death of a family pet. At least she had her puppy Ziggy in New York to help console her. Here's more:

RUMORS were swirling after Mischa Barton showed up an hour and a half late to her 21st-birthday dinner at Graydon Carter's Waverly Inn on Thursday night. Barton's table sat at 9 p.m., but the b-day girl, in a flowing white dress, didn't show until 10:30. Her guests were not angered but saddened to learn that the delay had been caused by the death of the starlet's family dog, Bean. Still up for celebrating, though, Barton ended the night with a bash at the Gramercy Park Hotel's Rose Bar.

Hopefully Mischa was able to pull it together and take her requisite 21-year-old tequila shots. Otherwise, how would Mischa initiate herself into the world of drinking? Right.
