The former pop star and his three-year-old girl were spotted at The Grove in Los Angeles where Disney Junior was celebrating the success of its acclaimed animated series, Doc McStuffins.
36-year-old Joey kept his outfit simple with a plain blue T-shirt, jeans and trainers, while Khloey looked adorable in a pair of flowery leggings, white trainers and a white blouse.
She also was seen clutching onto a toy lion, as she and her famous father posed for a few snaps.
One particularly sweet photo shows Khloey leaning in as Joey gives her a kiss - aww!
The three-year-old's godfather happens to be Joey's ex-bandmate and best friend Lance Bass.
Joey and Lance teamed up again in August along with fellow 'N Sync stars JC Chasez, Chris Kirkpatrick and Justin Timberlake.
The group reunited for the first time since their split in 2005 for a show stopping performance at the MTV VMAs, as part of Justin's incredible medley of hits.
Justin was awarded the prestigious 'Michael Jackson Video Vanguard' award at the ceremony and marked the huge honour with an impressive performance that included a highly anticipated 'N Sync reunion, as well as renditions of his solo hits including 'Suit & Tie', 'My Love' and 'Cry Me A River'.
