The actress was guest starring on sitcom 2 Broke Girls when she slipped into the virginal wedding gown.

Lindsay posed alongside 2 Broke Girls star Kat Dennings and he co-star shared the pic with the caption: ‘S**t gets real in upcoming episodes of 2 Broke Girls.’

The Mean Girls star plays bridezilla Claire Guinness in her cameo.

The star shared Kat Denning’s snap on her twitter page with the caption: 'Sharing with you guys a preview wedding moment on set #2brokegirls xo L.'

The snap comes just hours after her handwritten list of celebrity conquests was made public- though some names were blurred out for legal reasons.

A source who says she watched the star write the list said: ‘They were giggling and talking s**t about people in the industry. It was her personal conquest list. She was trying to impress her friends with the list and then tossed it aside.’

Stars such as Justin Timberlake, Zac Efron, Heath Ledger and The Wanted’s Max George were included on the list.
