New York, NY -- Justin Bieber's mom won't butt into his love life. Patti Mallette says she has "no idea" whether Bieber is on-again or off-again with Selena Gomez. She says her son doesn't want her getting involved. She's says she's learning how to let go of her son, who's 18.
She says she'll let him make his own decisions and his own mistakes. She says she didn't like seeing him post a photo of him mooning the camera on Instagram. She says it's hard not saying something when she hears reports of Bieber smoking pot. She says she has to "let him make some of his own mistakes" and hope that she "put the right things in him." Mallette is promoting a movie called "Cresendo" that she hopes will raise $10 million for centers that help pregnant girls.
