She's been working hard supporting Tom Jones on his national tour. 

And Megan McKenna took a well earned night off to celebrate her 29th birthday at Sexy Fish restaurant in Mayfair on Saturday night. 

The former TOWIE star-turned-singer stepped out with her blonde tresses slicked back into a bold statement plait which cascaded down to her posterior. 

Megan looked phenomenal as she showcased her flawless figure in a side split black bodycon midi dress. 

The reality star peered over a pair of statement wrap sunglasses as she entered the restaurant in the chic dress and brown stilettos. 

She completed her look with an enviable brown Prada shoulder bag and appeared to be in high spirits as she laughed with glee while entering the upmarket eatery. 

Megan couldn't get enough of onlooker's attention as she blew out kisses on her way into the sushi restaurant. 

Megan was joined for the wild night out by her younger sister Milly who looked gorgeous in an emerald green blazer. 

The pair laughed and joked as they hit the town in high spirits for Megan's lavish birthday celebrations.  

She stepped out hand in hand with her on-again boyfriend Josh Riley who cut a casual figure in black combat trousers and a matching bomber jacket.
