Tom Cruise stops to help up photographer who crashes to the ground amid movie ... trends now

Tom Cruise stopped to help up a photographer who crashed to the ground as the movie star arrived at Victoria Beckham's 50th birthday party on Saturday.

The American movie star, 61, grabbed the arm of the snapper as he lost his footing on the steps outside private members club Oswald's in London's Mayfair.

Mission: Impossible legend Tom's arrival caused much excitement outside the exclusive venue and as fans and photographers scrambled to get his attention, the man fell down.

Once the gentleman was on his feet, Tom headed into the exclusive club to celebrate fashion designer Victoria's birthday.

Tom looked smart in a black tuxedo which he teamed with a matching bow tied and a white shirt, while he shielded his eyes behind a pair of dark sunglasses. 

Former Spice Girl Victoria stunned in a semi-sheer floor-length green gown as she hobbled into the venue on crutches, following a gym injury, and prepared to celebrate the milestone with a string of her A-list pals.

Birthday Girl Victoria's elegant sleeveless dress featured ruffles at the waist and decorative floral detail to the side. 

Victoria was joined by her husband David who looked dashing in a black dinner suit which he wore with a matching bow tie and white shirt.

He arrived alongside the couple's daughter Harper, 12, who followed in her mother's stylish footsteps as she wore an elegant white satin dress and open-toed shoes in the same colour

Middle son Romeo, 21, wore a suit to match his famous father, as did his older brother Brooklyn, 25.

While Cruz, 19, donned a cream dinner suit which he teamed with a black bow tie and a pair of black and white brogue shoes.

The aspiring pop star completed his look with a pair of light brown braces and posed casually with his hand in his pockets.

Other guests included Eva Longoria as well as Victoria's former Spice Girls bandmate Geri Horner who attended solo after standing by under-fire husband Christian.
