There's still no official confirmation that Taylor Swift and Calvin Harris are dating, but all signs point to yet another famous-dude relationship for Taylor.
Heck, we've already seen Taylor and Calvin shopping at Whole Foods in matching shirts. and we literally can't think of anything more couple-y than that.
These two seem to be moving fast (There are even rumors that they're already in love.), but given Taylor's history with famous men, she's understandably concerned about being burned again, and sources say she's especially worried about Calvin's womanizing past.
"There's no doubt that Calvin has had a long string of female admirers," a source tells Radar Online. "He's also been a bit of a player in the past, but he wants to do right by Taylor.
"Calvin has enormous respect for Taylor, and he's been incredibly gentlemanly so far in their courtship. For that reason, her friends, knowing full well about his past reputation, are going to give him the benefit of the doubt and trust him with Taylor."
Harris dated Rita Ora for about 14 months before they went there separate ways in June of last year.
There were no allegations of infidelity, but apparently, Harris has been making the most of being single in the months since he and Ora split up.
He'd do well to keep it in his pants now that he's with Taylor. Dude's not famous enough to survive being torn down in a breakup song.
