Ben Affleck looks tough as he grabs coffee with assistant Gigi Fouquet after Jennifer Lopez divorce comments

Ben Affleck looked fierce during a coffee run in Los Angeles on Tuesday with his assistant Gigi Fogette – in the midst of his split from Jennifer Lopez.

Affleck has several movies in the works right now. Including the crime thriller RIP, which reunites him with his longtime collaborator Matt Damon.

This Tuesday saw him arrive on the sets of one of his projects and his face broke into a smile as he mingled with the crew.

Her latest sighting comes amid claims that Affleck feels he can't stop talking about their marriage and subsequent breakup.

Affleck reportedly didn't know she was planning to speak.

'Ben is known to talk about the breakup all the time,' an insider told DailyMail.com exclusively.

He prefers that she doesn't talk about it, but he feels that she always talks out. He wasn't sure he was going to talk about their relationship, but he figured it would eventually. It was as much a part of his life as anything else, and he was never going to leave it.

The insider says Affleck is 'okay with Jen no matter what' to deal with it,' and knows his ex is 'always talking' about her personal life.

The estranged couple called time on their two-year marriage in August, sparking months of speculation that they had hit the rocks for a second time.

“People deal with loss and breakup in their own way, and that's what Jen had to do and Ben had to accept,” they continued. 'He likes to keep things to himself, especially important details about their relationship.'

The On The Floor singer filed for divorce from Affleck on Aug. 20 after months of reports that their second romance had failed 20 years after their first split.

Lopez described her 'fundamental' breakup in an in-depth chat with Nikki Glaser this week, in which she talked about her life to her face.

“It feels lonely, unfamiliar, scary,” he told the comedian in Interview magazine. 'It's sad. It feels desperate.

But when you sit in those feelings and go, “These are not going to kill me,” I can actually find joy and happiness on my own. Being in a relationship doesn't define me.'

Lopez finally broke her silence on their failed union this week, describing her heartbreak at the fatal shoot for Interview magazine as 'sad' and 'terrible'.

Asked if she had any regrets, she replied: 'Not for a second. That doesn't mean it doesn't lead me well. It's almost over.'

Lopez, who did not mention Affleck by name, said that she is not looking for anyone right now and that her ex has not accepted all of his flaws.

'Someone who truly loves you will help heal those parts of you,' she said. 'What I've learned about love is that it's a safe thing. You make me feel safe and when I'm not great, you understand me and help me grow because you have your boundaries and I have mine.

The singer posed topless in leopard print bikini bottoms and matching gloves to mark the release's 55th anniversary.

Days after the interview, Affleck failed to crack a smile in a photo of himself scouting locations for his next project in Los Angeles.

Lopez and Affleck were famously engaged before splitting in the early 2000s. Conducting another ceremony a month later.

Their initial two-year romance was highly publicized and the intense scrutiny of their relationship was difficult for the couple to handle.

Speaking in her music documentary, The Greatest Love Story Never Told, which was funded and produced by Affleck's Artist Equity, she said: 'Ben and I broke up three days before our wedding and we crumbled under the pressure. You think you're fine, so let it go.

'He prefers that she doesn't talk about it, but he feels she's always going to talk out,' a source told DailyMail.com.

While navigating their reconciliation, two-time Oscar-winner Affleck admitted he didn't want to become a fixture on his wife's social media accounts.

The now-estranged couple's fears first surfaced in May when it was revealed they had gone 47 days without being photographed together.

Lopez attended the Met Gala and her film premiere alone for Atlas.

Speculation reached a fever pitch after Affleck moved out of his $60 million California mansion and moved into a $100K-a-month rental near his ex-wife Jennifer Garner.

A few weeks later, the home was quietly listed for $65 million and the couple began selling artwork from inside the mansion.

They reunited for the first time since announcing their split last month, together with their children at a Beverly Hills hotel.

Affleck shares Violet, 18, Finn, 15, and Samuel, 12, with Garner, while Lopez has 16-year-old twins, Emme and Max, with ex-husband Marc Anthony.
