PRINCE HARRY: British Prince Harry is to accompany new girlfriend Cressida Bonas to her half-sister's wedding in South Africa, The Sun reported Friday.
The 28-year-old royal and Bonas, 24, made headlines this week when they were photographed hugging and kissing during a Swiss ski getaway.
The Sun said Harry will be Bonas' date to Isabella Anstruther-Gough-Calthorpe's upcoming wedding to Richard Branson's businessman son, Sam.
Harry is also a friend of the groom and Bonas has been friends with Harry's cousins, Princesses Beatrice and Eugenie, for years.

MARK HAMILL: U.S. actor Mark Hamill says he and his co-stars from the original "Star Wars" trilogy are in talks to return for the sequels but haven't signed any contracts.
"They're talking to us," Hamill told "ET."
"George [Lucas] wanted to know whether we'd be interested. He did say that if we didn't want to do it, they wouldn't cast another actor in our parts -- they would write us out," he said. "We're in the stage where they want us to go in and meet with Michael Arndt, who is the writer, and Kathleen Kennedy, who is going to run Lucasfilm. Both have had meetings set that were postponed -- on their end, not mine. They're more busy than I am."
Hamill said he knows nothing for certain but suspects the new film will be about Luke, Han and Leia's children and grandchildren.
"Like my character would be sort of in the Obi-Wan range [as] an influential character," he said.
To be directed by J.J. Abrams, "Star Wars VII" is set for release in 2015.
