Renee Zellweger treated a stranger to a pair of designer shoes.
The Bridget Jones star met Bobbi Brown make-up artist Wendy Faracino in the shoe department of the Southampton branch of Saks Fifth Avenue while they were both admiring a pair of Manolo Blahniks last week.
A source told the New York Post: "Wendy was on her lunch break and was standing gazing longingly at the pair of Manolos when Renee strolled up to her and the pair began chatting about the shoes.
"A few minutes after she went back to work, the shoe department manager brought Wendy a gift-wrapped box and told her 'These are compliments of Renee Zellweger. She wanted you to have them.' It was the Manolos."
Renee is not the only star to indulge in spontaneous generosity.
Colin Farrell took a homeless man on a USD10,000 shopping spree earlier this month.
The Miami Vice star bumped into Toronto tramp Stress, who he had met before, and whisked him away to the city's Europe Bound Travel Outfitters store to kit him out in new clothes and street essentials.
The Irish actor strolled into the shop and demanded: "Get him anything he wants."
Store manager Dave Mott said: "It was like they were best buddies. The homeless guy was going around grabbing stuff."
The total bill came to a whopping USD2,100, but Colin's generosity did not end there.
The 31-year-old star then took Stress to a cashpoint, where he drew out a wad of USD20 bills for him. He also arranged to get Stress off the streets and pay the rent on a room for him for a year.
