The 35-year-old actress had a four-year relationship with Tom and despite their split in 2015, Sienna has revealed he remains her "best friend in the entire world".

The blonde beauty - who shares her four-year-old daughter Marlowe with the actor - said: "We still love each other.

"I think in a break-up somebody has to be a little bit cruel in order for it to be traditional, but it's not been acrimonious in a way where you would choose to not be around that person."

In fact, the closeness of Sienna and Tom's relationship has led to rumours they have rekindled their romance. But the actress has insisted they only stay at each other's houses because it provides stability for their daughter.

She told Harper's Bazaar magazine: "We don't live together, as has been reported recently, but we do half the time.

"Everybody will stay over or we'll all go on holiday and that's because we genuinely want to be around each other. It's great for our daughter that she has two parents who love each other and are friends."

Meanwhile, Sienna claimed recently that her party-loving ways damaged her career in the early days.

The 'Live by Night' actress has enjoyed an on-screen resurgence in recent years, but Sienna thinks she'd have had similar success when she was younger, if her personal life hadn't overshadowed her professional endeavours.

She explained: "I probably could have had all that I'm experiencing now if I'd been savvier and smarter.

"But I just wanted to have fun and not taper my behaviour in any way and it was hurtful, somehow, to my career.

"I grew up in the 90s watching everyone getting away with what they got away with. I was like, 'Oh the Gallaghers [did it], f**k it'."
