Cara Delevingne went to a gay strip club for her birthday.

The 'Paper Towns' actress turned 23 on Wednesday (12.08.15) and her model pal Suki Waterhouse treated her to a late night at the steamy venue in Toronto, Canada, to celebrate.

Earlier in the day, Suki, also 23, had shared an image online of herself along with TV presenter Poppy Jamie and model Clara Paget announcing they had arrived in the city for their best friend's birthday celebrations.

Alongside the image, she simply wrote: ''#CD23 crew has arrived. (sic)''

And later in the day, she added another photo of herself in front of the city with just a towel covering her modesty, writing: ''#Toronto CD23 (sic).''

And one fan took to Instagram to express his shock at seeing the star - who was taking a break from filming her new movie 'Suicide Squad' - in the strip joint.

He wrote: ''When you go to a male strip club and meet @caradelevingne her friends are the sweetest. @sukiwaterhouse you're amazing and so sweet and hope yall had the best time tonight. (sic)''

And to mark Cara's birthday, several of her famous friends wrote tributes to her online, including her girlfriend, St. Vincent.

The musician wrote on Instagram: ''Happy birthday to the one only @caradelevingne! (sic)''

Kim Kardashian West, Miley Cyrus and Taylor Swift were among other stars to flood her with well wishes, despite the fact they weren't present at the low-key party in Toronto.

Along with a screenshot featuring several random photos of Cara, Taylor wrote on Instagram: ''Happy birthday to cheeky, charming @Caradelevingne- who lights up my life..and regularly steals my phone & does this. (sic)''
