Shaken but not stirred: TOWIE star Sam Faiers gets in the mix as she creates her own cocktail at Hard Rock Calling

She is a successful businesswoman who owns a thriving clothes boutique in the heart of Essex.

But it would seem that Sam Faiers could have her sights set on becoming a mixologist too.

The Only Way Is Essex star was the star of the show backstage at the Hard Rock Calling event as she went from guest to barmaid in the blink of an eye.

She's a natural: TOWIE's Sam Faiers grabs some white rum for her cocktail and gets pouring as she turns barmaid backstage at the Hard Rock Calling event

The pretty blonde was attending day one of the three-day music event in Hyde Park in London when she decided that she's had enough of being waited on hand and foot.

So, after sweet talking a bar man into letting her go behind the scenes, she grabbed a shaker and some spirits and started to create her own cocktail for her fellow celebrities.

Not too much! Watched by a member of the Hard Rock staff, Sam carefully poured out a healthy measure of rum

Looking every inch the rock chick in her leather jacket and leopard skin print skirt, Sam, 20, started creating her own cocktail concoctions.

Sam, who owns Minnie's Boutique in Brentwood, Essex, then came up with her own and, in a nod to her boyfriend Joey Essex, she called it the 'The Reem Dream Mojito'.

It was a twist on a regular mojito, which contains white rum, sugar, lime juice, mint and soda water but Sam 'Reem'd it up' with some raspberry and mango.

And according to onlookers, her drink went down a storm with guests who couldn't get enough of the cocktail.

Pleased with her productive few hours, Sam then posed for some pictures clutching a Hard Rock Calling electric guitar, as she gave her best rock 'n' roll face as she pretended to play it.

And she wasn't the only one to try their hand at cocktail making - the cast of Glee also got in on the action.

Cheer up! Chris Colfer didn't look very happy as he sat with his cast mates backstage, including Ashley Fink, who plays Lauren Zizes

Currently in the UK performing a nationwide tour, several of the cast members, including Dianna Agron, who plays Quinn Fabray, and Chris Colfer, who plays Kurt Hummel, were among the young stars enjoying the gig and the backstage hospitality.

But it was Darren Criss, who plays Blaine Anderson, who got in on the cocktail action behind the bar of Rita's arms, a pop-up pub that was named in honour of Hard Rock waitress Rita Gilligan who started her career on the very first day of the opening of Hard Rock Cafe 40 years ago in 1971.

Also attending day one of the three-day festival was actor Matt Horne who came early to see the band James who supported The Killers.

And according to reports, he really wanted to meet Sam but unfortunately had to leave before she arrived.

Now in its sixth year, the Hyde Park event plays over three days and this year is headlined by The Killers, Bon Jovi and Rod Stewart.
