"After being fed by Justin Beiber (sic), Alex is one of JB's biggest fans! Justin really cares about the conservation of these beautiful animals! He is truly a class act and awesome guy!" the lion cub's owner, Alex Haditaghi, captioned the video of the "Baby" singer on Instagram.
Haditaghi and Bieber's paths have crossed before.
Haditaghi and Alex the Lion were at the same event Bieber was when he posed with the "abused" Bengal tiger as seen on Instagram.
PETA previously released a statement on their website condemning Bieber's play date with the tiger.
