They've officially taken another step together as a couple!
Calvin Harris has yet to make any statements about his current love life, but these pics of him leaving Taylor Swift's house early Tuesday morning kind of speak for themselves!
The 31-year-old DJ was spotted filling up his Range Rover on Monday before he made his way over to Tay Tay's Beverly Hills home where he apparently spent the night.
The duo wasn't seen out and about on Monday evening, so we can only imagine what they were doing during their night in together!

The 25-year-old pop star first brought Calvin to Nashville before letting him tag along to a couple of her best friends' concerts, and now she's even letting him sleepover, so…
We think it's safe to say things are getting serious.
Unless of course they really are just friends making music together, BUT WHO WANTS THAT!?
