Is Fergie morphing into Lindsay Lohan?

The pop star, 37, joined Instagram October 8 and shared a picture of herself in a floral robe and a long blonde wig. "What ever am I going to be for Halloween this year?" she asked. Though she's yet to reveal what her costume will be, Fergie looked nearly identical to Lohan, 26, before the Liz & Dick actress returned to her redheaded roots in early July.

Fergie recently taped an episode of Oprah's Next Chapter, airing October 21 at 9 p.m. EST on OWN. During her candid interview, the "Big Girls Don't Cry" singer opened up about her past crystal meth use, her dalliances with women and her future with Black Eyed Peas. She also addressed her husband Josh Duhamel's alleged affair with a stripper in 2009.

Lohan, meanwhile, is gearing up for the November 25 premiere of the Lifetime original movie, Liz & Dick, based on the late Elizabeth Taylor's torrid romance with Richard Burton. "Lindsay is great to work with," 44-year-old Grant Bowler, who plays Burton, recently raved. "She's pretty much Elizabeth Taylor reincarnated."
