Heidi MontagHeidi Montag has had a rough couple of weeks. Recently, she's ended her run as a reality television starlet on MTV's docu-soap 'The Hills' and separated from husband Spencer Pratt. She's filed for divorce (set to be finalized on Valentines' Day 2011, of course), and now, Pratt is shopping an alleged lesbian sex tape featuring Montag. And just last week, the surgeon responsible for the shocking 10 procedures she endured late last year, Frank Ryan, died tragically in a car accident. It's enough to make a girl go crazy.

But Heidi is keeping her beautifully-sculpted chin up, and has been dealing with the very public tragedies of her private life on -- where else? -- Twitter. Some highlights after the jump.
