Clearly, not everyone loves Justin Bieber, and Sunday night the singer found out for himself. When Bieber took his mom out to a Los Angeles Clippers game on Mother's Day, Bieber was booed by the entire crowd.

The 20-year-old pop star clearly was not welcomed at Sunday night's event as many spectators reacted to his presence with hatred-filled booing while he was sitting next to his mother. "The entire place booed him when Staples Center cameras put him on the jumbotron," a source said, E! reported.

However, the Canadian singer was not going to let that ruin his date with Pattie Mallette, as he was seen laughing and joking around, kissing her on the cheek and taking a lot of selfies with her. Also, he took to his Twitter account to post a bunch of sweet messages to let his 51.5 million fans and followers know how much he loves his mom.

Bieber shared a childhood photo of himself smiling with his mom right behind him, also smiling. "Happy Mother's Day to my amazing mom," he wrote in the caption with a hashtag of #HonorThyMother. "I love u with all my heart!"

Pattie Mallette, who has over 3 million Twitter followers herself, definitely enjoyed the NBA playoff game against the Oklahoma City Thunder. She tweeted: "Enjoying Clippers game w my favorite man for Mother's Day. Love you @justinbieber xoxo." She then posted more tweets later, saying, "Time together on Mother's Day at the Clippers game w my babyyy."

The news follows Justin Bieber's controversial antics that resulted in him being charged for driving under the influence, drag racing, resisting arrest without violence and driving without a valid license in Miami. He also currently remains under investigation for an egg-throwing incident, leaving his neighbor's house with thousands of dollars worth of damage. He could be charged with felony vandalism.
