Robin Williams' Daughter Zelda Celebrates New Year's in Sydney With Her Boyfriend: ''It Can Be Hard to Find Happiness When You're Sad''

Robin Williams' daughter, Zelda Williams, is ringing in the New Year Down Under.

Four months after her father's tragic death, the 25-year-old celebrated Christmas and New Year's Eve with her boyfriend, Aussie actor Jackson Heywood, in Sydney. Zelda has been documenting her holidays in Australia on Instagram.

Earlier today, Zelda posted an Instagram photo of the Sydney Harbour Bridge with the caption, "In about 7 & a half hours, this thing is gonna light up like the Fourth of July! New Years time!"

Zelda has also been sharing many snapshots of her sightseeing, including pics of wallabies, spiders and other animals at a sanctuary.

Zelda even posted an adorable beach photo of herself lying on her man's back on the sand by the water. "Human La-Z-Boy, much better than a beach towel," she captioned the sweet pic.

Zelda also took to Twitter the other day to reveal she's still mourning the loss of her father. "It can be hard to find happiness when you're sad, but it shouldn't be to find kindness. Thank you to all those being kind this Christmas," she wrote.

Zelda added from Australia, "Also, as I'm a day in the future from you all & thus past Christmas myself, happy future post-Holiday sugar coma!"

After Robin took his own life back in August, Zelda took to Twitter to react to the well wishes she received. "I just want to say thank you for all the stories and letters I've been receiving, especially from those who've also lost loved ones," she wrote, adding, "I don't come online often, but reading of others who have dealt with this loss & gone on to live happy, full lives is helpful. Truly."
