Even making a discreet exit through a side entrance, Brad Pitt and Angelina Jolie caused a stir earlier when sneaking out for dinner from the 45 Park Lane hotel in London.

A luxury five star hotel in Mayfair London, 45 Park Lane is one of the Dorchester Collection and has become a popular hangout for the rich and famous.

Although somberly dressed in black and grey – with obligatory sunglasses - there was no mistaking the stars. 

The 36-year-old actress added a touch of color to her outfit with an emerald Style of Jolie with Robert Procop necklace.

Pitt is in town promoting his latest film Moneyball – out later this week - and took the covers of Entertainment Weekly and Parade magazine this month.
