Work commitments meant she couldn't stay holed up inside, but that didn't mean Jennifer Aniston was ready to face the cameras.
As the newly-single actress left her New York hotel for her film set today she hid her face beneath an enormous hoodie, the Mail reported.
Perhaps Jennifer had yet to apply her lipgloss - by the time she left the theatre a few hours later she had pulled the hoodie back, and exposed her perfect make-up.
Yesterday reports surfaced that she dumped on/off boyfriend John Mayer over his obsession with micro-blogging site Twitter.
During the actress's trip to Europe earlier this month, to promote her new film Marley & Me, she was apparently infuriated when the musician claimed he was too busy to return her calls, but found time to update his Twitter page.
The couple split last week after a rocky 11-month romance, with John writing on his Twitter page, just days later, 'this heart didn't come with instructions'.
Following the split, Jennifer has thrown herself back into work after relocating to New York to start on her new comedy film The Baster.
The actress was spotted looking stony-faced as she left her Manhattan hotel clutching a script on Monday.
Singer John, 31, is one of the most high-profile Twitter users and updates his page on a daily basis.
A friend of the 40-year-old actress said she was unimpressed he found time to write random ramblings on the site, but not to contact her.
A pal claimed in America's Star magazine: 'John suddenly stopped calling her or returning her emails and when she would finally catch up with him, he'd say, “I've been so busy with work. I'm sorry I haven't had time to call you back."
'Jen was fuming. There he was, telling her he didn't have time for her and yet his page was filled with Twitter updates.
'Every few hours, sometimes minutes, he'd update with some stupid line. And in her mind, she was like, “He has time for all this Twittering but he can't send me a text, an email, make a call?"'
The couple decided to end their romance just days after Jennifer returned to the U.S.
During her trip to London, Jennifer hinted at possible romantic problems as she told the Mail On Sunday's You magazine it was naive for people to believe a relationship can last for ever.
When questioned about the perfect relationship, she said: 'I don’t have one and I don’t think it exists. We are just fooling ourselves if we think it does. Whoever said that every relationship has to last for ever?
'That’s hoping for too much. I think every relationship is a world unto itself.'
The split marks the second time they have called time on their relationship since they first started dating last April.
They originally parted ways in August with John holding an impromptu press conference outside his New York gym, informing the press it was he who had ended the relationship.
He said: 'There's no lying, there's no cheating, there's no nothing.
'People are different, people have different chemistry. I ended a relationship to be alone, because I don't want to waste somebody's time if something's not right.'
When the couple later reconciled, Jennifer said John immediately regretted his behaviour.
She told Vogue magazine: 'He had to put that out there that he broke up with me... Trust me, you'll never see that happen again from that man.'
At last month's Oscars, the couple appeared inseparable as they arrived at the Vanity Fair after-party together.
The event marked the first time Jennifer had come face-to-face with her ex-husband Brad Pitt and his partner Angelina Jolie.
Jennifer and Brad split in January 2005 after four years of marriage and the actor has since gone on to become the father of six children with his Mr & Mrs Smith co-star.
John is just the latest failed romance for the unlucky-in-love actress, who dated her The Break Up co-star Vince Vaughan for over a year and had a brief fling with English model Paul Schulfor, who is now dating Cameron Diaz.
