Justin Bieber and Selena Gomez have been testing out their skills as potential-parents, by babysitting Justin's half-brother Jaxson, 2 and sister Jazmyn, 4. The Baby-hitmaker and his girlfriend spent the weekend looking after the young kids in Los Angeles, reports the UK's Sun newspaper.

Justin looked a little worn-out as he was snapped carrying Jaxson, while Selena also looked weary as she walked on ahead. On Saturday (February 25, 2012), the couple attempted to get some welcome respite by taking Jazmyn to play at Malibu beach. The 17-year-old Canadian singer rocked a bright yellow t-shirt with dark sunglasses, with Selena matching her boyfriend's outfit by wearing a yellow sundress and denim jacket. Despite endless speculation of a split, Gomez appears to be content with her relationship with Justin and during the launch of the Disney Channel's new online game Superbia, said, "It's not worth pretending to be someone that you're not.I've conformed to be with guys that I've liked before.It's very easy to want to be what they want you to be, but it's no fun if you're pretending to be someone else".

The couple sparked rumors of an engagement last week, when Selena posted a picture of a diamond ring on Twitter. Some reports had claimed Bieber had proposed on Valentine's Day, though the speculation has since been played down.
