Justin Bieber spent quality time with his mom, Pattie Mallette, on Mother's Day. The two sat courtside together at the NBA Playoffs game between the Los Angeles Clippers and Oklahoma City Thunder in LA. When they weren't watching the Clippers hustle for their win, the mom and son leaned in close and posed for selfies. In a sweet mom move, Pattie had her phone ready to capture Justin as he showed off his basketball skills from their seats. Not everyone finds his behavior so amusing, though — Seth Rogen has been candid about his distaste for the pop star, most recently saying he's "a bit of a d*ck." On Thursday, Justin responded to the comments on Twitter, writing, "Seth Rogan sorry I didnt bow down when I asked 2 meet u was probably a bit shy and didn't want to be over the top but still. love ur movies." The complimentary response and fun outing comes after a rough few months for the singer, who was detained at LAX in April.
