Pretty princess: Katie Holmes takes Suri Cruise and a friend trick or treating in Beverly Hills yesterdayShe already picks out her own wardrobe, so it's no surprise Suri Cruise had the final say over her Halloween costume this year.
The 4-year-old was spotted shopping for a fairy princess outfit in Century City Mall with her mother Katie Holmes over the weekend before the pair headed out for trick or treating in Beverly Hills.
They strolled along the street with a young friend, dressed as Alice in Wonderland, before heading to a party with family and friends.
Just perfect: Earlier Suri picked out her own costume while on a shopping spree with her motherSuri's father, Tom Cruise, is currently filming Mission Impossible IV in Dubai.
Just this morning he was seen shooting stunt scenes for the upcoming film in which he was hanging from a rope off the side of the Burj Kahlifa building - the tallest free standing structure in the world.
Also out enjoying some spooky fun last night was Britney Spears' sons Sean Preston, 5, and Jayden James, 4, who got dressed up for a stroll round their neighbourhood.
Both boys were dressed as superheroes for the outing with their father Kevin Federline and his girlfriend Victoria Prince in Chatsworth, California.
They had bucketfuls of sweets - and here's hoping K-Fed, who has piled on the pounds since appearing on Celebrity Fit Club, managed to resist the temptation once they got home.
