Lindsay Lohan is the latest star to pay tribute to Happy Days creator Garry Marshall, who has died at the age of 81.
Garry, who also created Mork & Mindy starring Robin Williams and directed hit films including Pretty Woman, The Princess Diaries and Valentine's Day, died of complications from pneumonia after a stroke.
The star of Mean Girls and Disney's The Parent Trap - lately seen on the stage in London's West End - shared a photo of Garry, who directed her in his 2007 movie Georgia Rule.
Lindsay, 30, captioned the picture with a heartfelt recollection of the way the Beaches director took her under his wing.
She told her 4.7 million followers: "#GarryMarshall gave me an opportunity to be in the wonderful film Georgia Rule ... His beautiful family are so talented and caring In so many ways.
"More than that, when people doubted me, he didn't. He stood by me and for that I am forever grateful for another guardian angel in the heavens above."
She added: "#RIP & my love goes out to the Marshall family. Bless you. I thank Garry for his beautiful heart, work & wisdom."
Happy Days star Henry Winkler led the tributes following news of the film-maker's death.
