Maddox Jolie Pitt is his parents' guest of honor at Maleficent Private Reception.

Angelina Jolie, 38, and Brad Pitt, 50, looked as proud as can be when their son, 12-year-old Maddox Jolie Pitt accompanied them on the blue carpet on Thursday evening.

The trio attended a private reception at Kensington Palace for upcoming Disney movie, Maleficent, in which props and costumes from the movie were exhibited in aid of Great Ormond Street hospital.

Angelina plays the title role of the evil horned fairy in the movie and daughter Vivienne stars as the young Princess Aurora, while son Pax and daughter Zahara have cameo roles.

Elle Fanning, 16, plays Sleeping Beauty Aurora and actor Sam Riley, plays a character called Diaval in the film.

Jolie looked incredible in an embellished floor-length black gown by Atelier Versace, which had a plunging neckline and a low-back detail.

Her beau, Brad was dressed head-to-toe in matching black, topping off the look with a pair of ultra trendy specs.

Maddox looked cute in a black shirt and skinny jeans, which he livened up with a red tie and a cool leather jacket. He wore his hair slicked back and looked thrilled to be with his parents.

Also walking the blue carpet that evening was 16-year-old actress, Elle Fanning, who looked like she had just stepped out of a fairytale in her romantic-looking get-up.

According to imdb, the film tells the tale of a vindictive fairy that is driven to curse an infant princess before realising the child may be the only one who can restore peace.

When Angelina makes her red carpet appearances, you're almost always in for a jaw dropping moment, and this is nothing less. With the floor length, sequins running through it, draped neckline and ruching throughout, this gown is pure class.

And we expect nothing less from Versace. Donatella - a good friend of Angelina - knows a thing or two about glamour and statement making. She is the queen of sexy vamp, and this dress, although conservative in its showing the flesh, offers up lots of star quality.
