He has long been compared to British star Tom Hardy and has acknowledged the similarities between them, but pointed out he actually has a twin-brother called Taylor. 

He told Elle.com: 'I'd be honoured to be in the same sentence as Tom Hardy. I've been a twin since the day I was born - fraternal, but we look a lot alike - so I've already been mixed up with another man my entire life.'  

On Monday, Sarah dressed in a nude long-sleeve Donna Karan New York top, Maison Margiela denim skirt, and Maison Margiela white Mary Janes selected by costume designers Molly Rogers and Danny Santiago.

Meanwhile, Logan was seen in a grey 'Dead Wait' T-shirt French-tucked into belted blue jeans as he carried Carrie's runaway cat Shoe back to her home.

In the season two finale, the Virginia-based furniture designer informed Carrie he needed a five-year break from her in order to focus on his troubled teenage son after she sold her beloved West Village apartment to fit his three sons.

Sharing her excitement over what's in store for the HBO drama, which resumed filming in March, Jessica said: 'The city continues to be this banquet of opportunity.

'We have these wonderful new cast members, who are no longer new, so there is that.

'And I think that Carrie is at a point in her life when this unthinkable event happened and then she realized that life is short and now it's time to evolve and commit more so to being the relevant person she wants to be.

'So, what does that mean? And where might that take a person? And Aidan does play a somewhat significant part of that quest, so we're excited.'
