Justin Bieber not only knows how to woo the ladies, he also knows how to treat his mom on Mother's Day. 

Bieber caused quite a stir Sunday as he took his mom shopping at the Grove mall in Los Angeles.

"I'm here shopping for my mom to celebrate Mother's Day," Bieber told E! News when asked why he was standing in the all-female clothing store chain Forever 21.

The singing sensation, who was also accompanied by a bodyguard and a male friend, managed to blend in with the crowd at first, sporting jeans, sneakers and a white T-shirt.

But according to an eyewitness, his cover was soon blown.

"Young female shoppers quickly realized it was him and started whipping out their cell phones to take pictures from afar," the onlooker told E! News. "He was super easygoing with it all and was smiling the whole time."

Bieber and his mother left the store empty-handed, but they continued to shop and hang out at the outdoor mall, stopping at Guess and grabbing lunch at the Cheesecake Factory. The teen sensation even managed to work in some skateboarding.
