A fan obsessed with Ariana Grande managed to knock on her front door in order to hand her a creepy love note, bypassing all the security measures the singer had put in place.

The man, who is in his 20s but hasn't been named, was apprehended by police in Los Angeles after brazenly showing up at her home around 2pm on Saturday, knocking on her door and even asking the person who answered to speak to her.

Luckily Ariana wasn't home at the time, but the man refused to leave until cops showed up, TMZ reports.

When police arrived, the fan was found lurking nearby her house and had a love note in his possession with directions to her home.

He allegedly spat on officers while being arrested, and has been booked for misdemeanour trespassing and felony battery for the alleged spitting.

It comes after Ariana angrily urged her fans to socially distance themselves during the midst of the coronavirus pandemic.

"Your hip hop yoga class can wait I f**king promise," she snarked in response to some followers vowing to continue life as normal, despite advice in the US and UK to take extra precautions to avoid contracting and passing on the killer virus.

Taking to her Instagram Story, Ariana went on: "I keep hearing from a surprising amount of people statements like - 'This isn't a big deal' / 'We'll be fine' / 'We still have to go about our lives' - and it's really blowing my mind.

"I understand that is how [you] felt weeks ago, but please read about what's going on. Don't turn a blind eye. It is incredibly dangerous and selfish to take this situation that lightly."

She added: "The 'we will be fine because we're young' mindset is putting people who aren't young and/or healthy in a lot of danger. You sound stupid and privileged and you need to care more about others. Like now."

The Thank U, Next singer got angry over Twitter when some fans pointed out her $50million net worth means she's not at risk of losing her home or job as a result of not being able to go to work.

"'Well some of us have to work!' I understand and entirely support your frustration. I do not mean to disrespect anyone who doesn't have the privilege of cancelled work or being able to call out of their work," she tweeted.

"But, this is a national emergency and a pandemic of global proportion. I am agreeing [with] y'all. These are the times when the world should rely on their governments to support the plan for all citizens to stay at home and lessen the threat of infection and the spread of the virus."

She continued: "Please support h.r.6201 which has passed the house. This bill will provide people [with] necessary financial support in terms of paid sick leave / unemployment due to corona virus / isolation / prevention! Please contact your senate to support the passing of this bill! Urgently.

"Instead of responding with your frustration (that I totally agree with and support) call your senators! We need them to support this plan. Everyone deserves to be financially supported and feel safe at home during this time."
