Teen superstar Justin Bieber helped rocker Travis Barker earn major cool points with his seven-year-old daughter on Friday (24May13) after stopping by their Los Angeles home to hang out with the youngster.

The Baby hitmaker posed for a photo with little Alabama on his motorbike and she became the envy of all of her friends when she posted the picture on Instagram.com later that day.

In the accompanying caption, she wrote, "Justin Bieber came by and I took a picture with him on his motorcycle. He is really nice and he brought me a sk8 (skate) board".

Bieber sent the Blink-182 star a link to the snap via Twitter.com on Tuesday (28May13) and complimented him on his "cutie" of a kid, prompting the proud dad to reply, "Thanks, you made her day".
