Rosie O'Donnell seems to be staying positive amid the past difficult months.

Has Rosie O'Donnell Moved On From Michelle Rounds?

Not only did her father die last August, but the TV personality also got divorced from her wife, Michelle Rounds. And to make matters a lot harder, O'Donnell's daughter Chelsea gave an interview on how she has no desire to be part of her mother's life anymore.

But it was previously announced earlier this month that O'Donnell would guest star on CBS sitcom Mom as the ex of Allison Janney's character, according to People. And based on what the celebrity posted on Instagram over the weekend, she seems to be having a blast. She added in the caption that she had the "best time ever!!!"

With a successful career to focus on, O'Donnell can have other things to keep her distracted from any difficulties she may be going through.

When her daughter spoke to Inside Edition about her troubled connection with her mother, she admitted that she doesn't even love her.

"I care about her and I hope she's doing well," Chelsea said about Rosie via Entertainment Tonight. "But love is a big word and I wouldn't really use that."
