Screw rehab, the best crisis management tactic in the business these days seems to be a sitcom cameo. Just ask Brit-Brit Spears, whose star turn in How I Met Your Mother clocked the show's highest numbers ever. (And marked a successful PR gambit signaling the starlet's return to the straight and narrow.) Hot on the heels of that blockbuster cameo, everyone's other favorite embattled, drug-addled -- hey that rhymed! -- trainwreck is jumping on the proverbial bandwagon. Lindsay Lohan is rumored to once again be negotiating a guest appearance on Ugly Betty. Word is Ms. Blow-han will pop up on the show's season finale and return next season for an eight-episode stint. Assuming she keeps her, uh, nose clean. Early reports tell us Linds will be playing Betty's blue-collar, burger slinging pal, which will be a much bigger stretch than Lohan's previous filmic incarnations as a catty bitch (Mean Girls), a stripper (I Know Who Killed Me), a bratty teenager (Georgia Rule) and a lead-footed driver (Herbie: Fully Loaded). Truth be told, I'm hoping she exceeds my (low) expectations. Much as her former co-stars are always insisting that LiLo really, truly is a genius thespian, albeit a misunderstood one, I've yet to see her top her performance in The Parent Trap. So consider this a challenge, Miss Thang. The gauntlet hath been dropped.
