The actor was previously married to Aniston from 2015-2017 and the pair have remained on great terms since their split.

In a rare, candid interview earlier this year, Theroux himself revealed that the exes still keep in touch through text, Facetime, and phone calls.

And a few months earlier in November, Jennifer in an interview also alluded to their close friendly relationship by revealing Theroux had recently dropped by her home at the time.

The Hollywood star first lost her mother, Nancy Dow, with whom she had a strained relationship throughout her career, in 2016.

She was also estranged from her father for years, but had been on good terms with him at the time of his death.

Prior to her marriage with Justin, she was wed to Brad Pitt, 59, from 2000 until 2005. 

He then fell for Angelina Jolie with whom he shares six kids: Maddox, 22, Pax, 19, Zahara, 18, Shiloh, 17, and twins Knox and Vivienne, 15. Their ugly and very public battle over custody is still raging.

Aniston recently admitted that she finds it 'easier' to be single.

The star, who has also has dated the likes of John Mayer in the past, admitted that she was never excited to pursue adult relationships after seeing her parents divorce.

In a recent conversation with the Wall Street Journal, Aniston reflected on how her late parents' relationship has affected the way she dates.

'It was always a little bit difficult for me in relationships, I think, because I really was kind of alone,' she admitted.

'My parents, watching my family's relationship, didn't make me kind of go, "Oh, I can't wait to do that,"' she said of her mom and dad, who divorced when she was a little girl.

The movie star revealed, 'I didn't like the idea of sacrificing who you were or what you needed, so I didn't really know how to do that. So it was almost easier to just be kind of solo. So I didn't have any real training in that give-and-take.'

Jennifer went on to say: 'It's just about not being afraid to say what you need and what you want. And it's still a challenge for me in a relationship.'
