She must not care he hooks up with other girls right under her nose!

Justin Bieber will reportedly attend Selena Gomez's upcoming 22nd birthday bash at a private estate in California, E! News reports.

The "Come & Get It" singer's turns another year older on July 22, and she is in the beginning stages of planning her party. The only problem? The rest of the guests don't want The Biebs anywhere near the birthday girl!

"No one wants [Bieber] to go. All her friends want him out of the picture and just want her to have a relaxing birthday with no trouble and they think he's going to dominate her attention," an insider tells the news outlet.

"She doesn't seem to care that he spends time with other women and isn't always honest with her. She's hypnotized. Her friends just want her to enjoy herself for her birthday, but if Justin attends it might complicate matters," the source added.

She should wish to be cured of Bieber fever when she blows out her candles!
