Pucker up! Boyfriend Pete Wicks looked proud as punch as he supported Megan Mckenna during her live singing debut

Having performed in a slinky silk floor-length red gown, she put her toned curves on display on stage.

The figure-hugging strappy number hugged her slender physique to perfection, and she later changed into a more casual black ensemble.

Hugging her beau Pete, who looked handsome in a poloneck jumper, black chinos and a grey well-cut blazer, they appeared every inch the loved-up couple.

Pulling Megan close, tattooed Pete planted a kiss on her cheek affectionately as they celebrated her success.

And Megan's dad Dave McKenna was also there to support his daughter, posing alongside cheerily alongside Pete.

Megan's parents featured heavily in TOWIE scenes during which Pete wooed Megan back following his sexting scandal over the summer.

Earlier in the night- despite being better known for her dramatic escapades on ITVBe's The Only Way Is Essex, Megan looked every inch the theatre pro.

Worlds away from her reality star counterpart on Sunday night,she made her West End debut in Kristina Rihanoff and Gleb Savchenko's production One More Dance.

Singing her heart out onstage at the Adelphi Theatre, the reality star truly dazzled in a slinky red satin number as she first wowed the audience with her powerful voice.

Number one fans: Supporting her on her big night was of course her two number one fans - boyfriend Pete Wicks (R) and father Dave McKenna (L)

Although taking her moment in the spotlight to perform rather than partake in her usual antics in Essex, Megan did not let her usual glamour falter as she took to the stage in an array of stunning ensembles. 

Remaining classic in style and the one crimson hue all the way down, the simple dress helped Megan to stun on the stage whilst not detracting from the night's main focus - her vocals. 

The TOWIE lass later changed into an angelic white gown, which injected a hint of glitz into the evening with chic embellished shoulder panels.

Red hot! Megan did not let her usual glamour falter as she took to the stage in an array of stunning ensembles, including a figure-hugging red satin frock

The floor-length gown also remained its soft and feminine cream colour throughout - but nipped in gorgeously at her middle to enhance her enviably petite waist and flat stomach. 

With her trademark voluminous tresses slicked back, the reality star-come-singer oozed old-school glamour as she passionately sang in front of the dancers for the sold-out audience. 

Supporting her on her big night was of course her two number one fans, boyfriend Pete Wicks and father Dave McKenna - who suited and booted themselves up for the special occasion.

After making a name for herself on the likes of Ex On The Beach, Celebrity Big Brother and of course, TOWIE, Megan has now taken centre stage something far more creative - singing.

Having bonded with Kristina Rihanoff during their time in the CBB house earlier this year, Megan stayed in contact with the former Strictly Come Dancing star and was consequently cast in her West End show, alongside Gleb Savchenko, earlier in the year. 

Kristina listened to Megan sing while they spent the same season of CBB together and booked her for the one-night-only show last month, when Megan said how 'thrilled' she was to be asked.

'I didn’t have to think twice,' she said of the casting. 'Making my West End debut singing on stage with some of the most talented dancers in the world accompanying me truly is a dream come true.'

The TV personality has been desperate for years to be recognised for her singing ability more than anything else, and her slog through the realms of reality TV has finally allowed her to do this.

Before the show on Sunday she treated fans who wouldn't have been able to get their hands on tickets to the event with photos of her backstage in the stunning cherry red gown.

Beaming: As she left the theatre following the performance, the look on her face proved the night went well

She posed for the camera in the satin floor-length backless number, showing off her delicately curled brunette locks which she wore loosely behind her shoulders.

'It's show time!' was her caption, before posting a second shot of her in the wings with an array of backstage crew around her, holding out her dress's train in all directions, creating an almost winged effect.

'Just chilling backstage...' she quipped in the caption.

Clearly not feeling the Christmastime chill in the air, the adrenaline-filled TOWIE star grinned ecstatically as she walked along the street outside the theatre, accompanied by a gaggle of women, one of whom grabbed her hand proudly.

The show featured Ballroom and Latin American dance routines, starring Gleb and Kristina.
