Lions, tigers and bears... make for a romantic afternoon date. Justin Bieber and Selena Gomez were spotted spending some quality time together at the Los Angeles Zoo on Sunday, June 22. According to E! News, the on again, off again couple had a private tour and posed for pictures with fans.

Genie Vasels, vice president for Institutional Advancement of the Greater Los Angeles Zoo Association, told E! that the pop stars arrived to the zoo around 2 p.m.

"The occasion was Justin's grandparents were visiting from Toronto and he wanted to do something nice for them," Vasels said. "So he brought them and Selena, two bodyguards and his assistant to the L.A. Zoo."

"They were very affectionate with each other and they held hands throughout the day," he continued about Gomez and Bieber. "The grandparents were equally lovely and everyone was just enjoying having a fun family outing."

The "Boyfriend" singer also posed for pictures with fans and posted a shot of himself with his arm around a young girl in a wheelchair on Twitter.

"He went on his own and put his arm around her and it was a very sweet moment and he took some photos with her and her parents," Vasels told E!. "No one asked him to do it but he did this on his own volition."

Bieber and Gomez recently rekindled their relationship again but apparently the romance is ruining Gomez's friendship with pop star Taylor Swift. Reportedly the "Red" singer is fed up with the back and forth relationship.

"Taylor is completely baffled that Selena has yet again taken Justin back," a source told Hollywood Life. "She thinks that Selena is a lost soul and nothing will make her realize how bad Justin is until she no longer has a career. Taylor is convinced that this relationship has and will ruin her health and life but she is finished with trying to help, she feels like she has tried enough and it hasn't worked."
