It’s likely, she and her staff were being tested for the highly contagious viral infection, which has surged across the country due to recent holiday gatherings.

The Grammy nominee’s outing comes amid news that Armie Hammer reportedly stepped down from his leading role in her upcoming romantic comedy Shotgun Wedding after disturbing messages allegedly sent by the actor were leaked.  

A Wednesday report from PageSix claims that the actor is already exiting the project, with a production spokesperson saying: ‘Given the imminent start date of Shotgun Wedding, Armie has requested to step away from the film and we support him in his decision.’

Meanwhile another article claimed that Lopez had also been considering dropping Hammer from the film.

‘Jennifer is very concerned about the movie now these stories have come out,’ a source has told The Sun.

A source expanded to the outlet: ‘There have been a lot of phonecalls and meetings about if they can still make the movie with Armie as the romantic lead.

‘A lot of people have suggested quietly dropping him from the project and I think Jennifer could agree to it,’ the insider added.

‘She’s a producer on the movie – does she want to act with him and pretend to be in love with someone who’s been accused of texting those things?’

‘Does she want to act with him and pretend to be in love’: JLo currently is cast as Hammer’s fiancee in the upcoming rom com

JLo, who is reportedly ‘horrified’ by the alleged messages, currently is cast as Hammer’s fiancee in the upcoming rom-com.

DailyMail.com has contacted reps for Lopez, who did not immediately respond to comment.

The news broke after a series of screenshots leaked over the weekend, purporting to show Hammer authoring a series of disturbing messages about rape fantasies, cannibalism, and ‘blood-sucking’ to a woman over a period of four years.

The actor is yet to speak publicly on the matter, and multiple requests for comment sent to his representatives have so far gone unanswered.

Upset: In an exclusive interview with DailyMail.com on Tuesday, a close friend of Hammer's estranged wife Elizabeth Chambers said the actor's former spouse is ''shocked and sickened' by the messages

The controversy involving Hammer was first stirred up on Sunday when a series of screenshots showing graphic messages he’d allegedly penned to a woman were leaked by the anonymous, now-private Instagram account, House of Effie.

The alleged messages, said to be sent between October 2016 and February 2020, include conversations about BDSM, in addition to numerous sexual references to cannibalistic acts and ‘blood-sucking.’

In one exchange, Hammer is seen to write: ‘I am 100% a cannibal. I want to eat you.’

Complicated: The two announced their 10-year marriage was over in July, as a source close to Chambers admitted she was aware of his infidelities, including being romantically involved with Rebecca co-star Lily James as DailyMail.com revealed last year, which led to their split; seen in 2018

‘F**k. That’s scary to admit,’ the message continues. ‘I’ve never admitted that before.’

The authenticity of the screenshots has not yet been verified, however the woman behind the House of Effie account shared new alleged correspondences with Hammer on Tuesday, in which he appeared to refer to her as his ‘slave.’

‘You just live to obey me and be my slave,’ a message purported to have been sent from Hammer’s official Instagram account reads. ‘I will own you. That’s my soul. My brain. My spirit. My body. Would you come and be my property till you die?’

The message continues: ‘If I wanted to cut off one of your toes and keep it with me in my pocket so I always had a piece of you in my possession?’ 

Disturbing: Hammer and Elizabeth Chambers were still married at the time the alleged messages from Hammer were apparently sent to the woman

But Hammer’s alleged extreme kinks are a ‘complete shock’ to the mother-of-two, with the friend adding: ‘Armie appears to be a monster.’
