Tom Hanks' son has got married.

Colin Hanks - who recently starred alongside his father in 'The Great Buck Howard' - tied the knot with publicist Samantha Bryant at the London West Hollywood hotel in Los Angeles on Saturday (08.05.10).

According to website E! Online, around 300 guests - including director Steven Spielberg - were in attendance for the nuptials at the rooftop pool area of the hotel.

Guests staying at the complex had been asked to leave the pool at 3pm on Friday (07.05.10), but were offered free drinks to make up for the inconvenience.

Colin - whose mother Susan Lewes, Tom's first wife, died of cancer in 2002 - got engaged to Samantha last June after several years together.

Speaking about their union, the 'Orange County' star said last year: "We had the same group of friends and knew of each other, but never paid attention to it."

Colin's stepmother Rita Wilson was so pleased when the couple got engaged, she gave Samantha a $10,000 designer handbag to congratulate her.
