In Buzz Makers this week, William and Kate finish their North American tour, Kristen Stewart hangs out with Robert Pattinson on set, a look at the 'Harry Potter' stars over the years, David and Victoria Beckham welcome a baby girl, and Ted Danson joins "CSI."

On Monday, Prince William and Kate Middleton wrapped up their North American tour by finishing up in Los Angeles. The couple had met some of Hollywood's elite, but also had time to take in a polo match and meet with various charity groups.

Kristen Stewart was seen visiting Robert Pattinson
on the set of his new film, David Cronenberg's 'Cosmopolis.' Kristen also brought along the dog they reportedly adopted together earlier this year, Bear, to the set with her. The two will be seen on screen later this year in 'The Twilight Saga: Breaking Dawn – Part 1' out in November.

'Harry Potter and The Deathly Hallows Part 2' was released this week and saw the end of the popular film franchise. ET took a look back at the three leads, Daniel Radcliffe, Emma Watson, and Rupert Grint, as
they grew up along with the series.

David Beckham and wife Victoria welcomed their first daughter to the family this week. "[The Beckhams] are delighted to announce the birth of their daughter," David's spokesman Simon Oliveira tweeted on Sunday. The couple's first girl named Harper Seven was born Sunday morning at Cedars-Sinai Medical Center in Los Angeles, weighing 7 lbs., 10 oz.

Ted Danson was announced this week as a new regular for the TV series "CSI: Crime Scene Investigation." Danson will be replacing Laurence Fishburne who took over when Wiliam Petersen left the cast in 2008. The new season of "CSI: Crime Scene Investigation" begins September 21, 2011.
