She started out Halloween weekend posing for racy selfies in hot pink lingerie, before proudly sharing the results of her camera work on Instagram.

But as the big day rolled around on Monday, Linday Lohan, 30, was in full costume mode as she stepped out dressed as Suicide Squad favourite Harley Quinn to attend party planner Fran Cutler’s Halloween bash in London.

The actress made her way to South Kensington’s exclusive Albert’s Club in red-and-blue sequinned hotpants, teamed with fishnet black stockings and black booties.

Jo Wood was also at the party, sharing an affectionate hug with her builder ex Paul Scarborough, from whom she split in 2012, amid claims of infidelity.

Over the weekend, Mean Girls star Lindsay flashed a lot more flesh as she shared a snapshot of herself posing in lingerie. 

Looking body confident in the two-piece, the flame-haired beauty captioned the image with the words: ‘#halloweencostume #halloweenisaworkout #halloween #everydaywewearpink and no filter.’ 

Looking naturally beautiful, the superstar flashed her toned abs in the ensemble as she posed in the hallway, with her arms outstretched.

Her social media offering came after a plea for her to get in touch with Kettering’s MP last week.

The star famously angered residents of Kettering during the Brexit vote in July after admitting she had no clue where the English town was.

Now the town’s MP has called on the American actress to make good on her promise to turn on the Christmas lights after she failed to get back in contact.

The actress has been asked to contact the Northamptonshire town’s officials after she was invited to switch on the festive display by local MP Philip Hollobone and Commons leader Chris Grayling to make up for her June comments.
