Actor Athiya Shetty posted a photo on Instagram today to wish her father Suniel Shetty on his birthday. 

And one of the 757 comments on the picture was from the international celebrity rapper Drake. 

Drake - whose kiki challenge spurned everyone into 'accidental' dancing - commented on the post and Athiya responded to the comment as well. 

And the social media just could not digest this latest Hollywood-Bollywood crossover.  

Confused netizens flooded the internet with questions, trying to figure out a mystery bigger than black holes - how did the two stars know each other? 

Apparently, the two actually met in London this summer when both were on a holiday. And clearly stayed in touch even when the holiday ended. In fact, the two frequently like each other's pictures on Instagram.

It definitely looks like the start of a 'legendary' friendship!
