Ever since Season 4 of Arrested Development premiered on Netflix last week, many viewers have been scratching their heads — and not just about the new recurring ostrich motif.

Portia de Rossi, who reprised her role as "activist" Lindsay Bluth-Funke, looks vastly different on screen than she does in more recent interviews and photos. The noticeable change in her appearance has led many viewers to wonder whether de Rossi had had plastic surgery.

But that's not the case, according to E! Online. "She's absolutely not had plastic surgery," a source tells the site. "Her character is clearly wearing a wig, which ended up altering her entire look."

It seems to be a lot more than a wig that's different about Lindsay's look, but de Rossi and showrunner Mitch Hurwitz have yet to comment on the rumors. Some fans speculate that the jarring difference may have been intentional, to imply that the vain and self-absorbed Lindsay had a botched plastic surgery in the seven years between Seasons 3 and 4.
