What are the most important milestones in the early stages of a relationship?

Meeting the friends, meeting the parents, going on holiday together... we're avoiding the bedroom-based stuff here obvs.

You'd better add pet-sitting to that list anyway - because superstar dance producer/pop star Calvin Harris has just taken that big step in his romance with Taylor Swift.

Yep, the 31-year-old Scotsman has been looking after T-Swizzle's beloved moggy Meredith while she's away on tour.

And just when we thought there were enough cat videos on the internet, he's shared an impossibly cute slo-mo clip of her drinking from a tap.

Well at least if the pop career dries up he could always go full-time with the pet-sitting.
