Earlier this week, the Shameless actress was a guest on SiriusXM's Sway in the Morning where she revealed she has the unfortunate position of being the 21-year-old's new victim neighbor.
Being the lady that the 28-year-old is, she tried to greet her new pal… but was denied!
The opera singer confessed:
"Justin Bieber just moved into the house next door to me… He's my new next door neighbor and I went over to offer him a neighborly hello and I'm not going to do that anymore cause he has a ton of bodyguards there and they're really scary."
However, the Poseidon star did catch a glimpse of the pop star where he apparently was trying to do his best rendition of Kanye West and Jay Z's hit song N—– in Paris!
The New York native said:
"He pulled up in his Bentley and then went inside…he was actually rapping as he got out of the car. He was like, ‘Ball so hard motherf—kers wanna'… and I was like, yup, Justin Bieber is my neighbor, that's cool."'
She HIGHlariously added:
"I'm not going to ask for a cup of sugar over there."
However, will Miz Rossum join the Biebs at one of his highly-publicized shindigs?!
