Sticking up for LiLo! 2 Broke Girls stars Kat Dennings and Beth Behrs have slammed a recent story that Lindsay Lohan was hard to handle while filming an episode of their CBS comedy. The trouble-prone actress recently stopped by the show for a guest starring role, where she donned a white wedding gown.

"This article is complete bullsh-t. Lindsay was prepared, sweet to everyone, & professional. Not nice to spread lies," Dennings, 27, tweeted on Friday, March 14.

"This article isn't true. I second @OfficialKat," costar Behrs, 28, added. "@lindsaylohan was kind to everyone, professional and knew her sh-t."

Dennings and Behr's tweets are in reference to a sketchy story published on the site Contact Music, citing a blog allegedly written by an audience member that experienced Lohan's visit firsthand. The eyewitness claimed that Lohan, 27, allegedly had to have her lines changed because she kept forgetting what to say.

Lohan, meanwhile, looks to have had nothing but a good ole time during her sitcom visit. "Sharing with you guys a preview wedding moment on set. #2brokegirls xo L," she wrote on March 12, with a photo montage of herself next to the cast on set. She also shared a snapshot of herself about to get dolled up in hair and makeup.
