Justin Bieber indirectly acknowledged he was photographed smoking pot at a party and chalked up the embarrassing incident to a youthful mistake. He promised his fans not to let them down.

The photos surfaced on gossip site TMZ and were taken one day after photographer Chris Guerra was struck and killed by a car. He was photographing Bieber’s Ferrari, while it was pulled over by police.

Justin Bieber Spotted Smoking Pot After Paparazzi Death

Guerra told a friend he thought he saw Bieber smoking a marijuana pipe in his car earlier in the day. When he saw the conspicuous car leaving the Four Seasons hotel in Beverly Hills he followed it.

Behind the wheel, however, was Bieber’s pal Christopher Moore, also known as rapper Lil Twist.

The teen sensation’s reps heatedly denied that Bieber was smoking pot, and accused the dead paparazzi of harassing and stalking the singer. Bieber expressed his condolences, but was photographed at the party laughing and holding an obvious marijuana “blunt” in his hand.
