If she really wanted to remain incognito, a night of reality TV and a takeaway might be advisable.

Instead, limelight-addict Imogen Thomas feigned shyness as photographers tried to snap her picture.

The former Big Brother contestant was seen emerging from Russian restaurant Novikov, but instead of her usual flirtatious smiles and spilling cleavage, lo and behold, Imogen covered her entire face.

The 29-year-old held a skull print
scarf over her head, hiding her upper body – although perhaps it would
have had a slightly more dramatic effect had it not been see-through
chiffon.

She also pretended to coyly peer out from a wall, using it as a shield for protection.

Yet,
true to character, it wasn't long before the glamour model was enjoying
the attention by flashing her Cheshire cat grin as she paraded her bare
legs in ruby slippers and a prom queen white dress.

She also clutched a red bag and a rose, presumably to present to boyfriend Adam Horsley after her girly night out.

Imogen, who was out celebrating her
friend's birthday, had paid a visited to the hair salon earlier in the
day for a cut and colour change – not really the antics of a lady who
doesn't want to be noticed.

She tweeted: 'Thank u @Georgevallossian for giving me an amazing hair cut and colour. Love it šŸ™‚ x'

While she looked typically and stylish, Imogen is caught in a constant battle with her weight.

However, the pretty brunette has dropped a dress size, going from a 12 to a 10, coinciding with her new role as the spokesperson for a new slimming product known as Slimsticks.

Imogen revealed: 'My problem is that I
absolutely love food so I find it difficult to control my weight. I
have tried many diets but never stuck to them because they stop me
eating the foods that I like.'
