“You are flying back to the USA today. Dropping you off at the airport and waving goodbye, it never gets easier. Thank you for the most wonderful adventures these last few months,” the Dancing With the Stars winner captioned a sweet pic of herself with Chandler.

“We even got to celebrate your 20th birthday here in Australia together, hiking through the Great Dividing Range! I’ve known you since you were 16 and every day, from the very first day I met you, you’ve been my sunshine,” Bindi continued.
