The 'Blank Space' singer - who was originally reported to be taking her new romance with the 31-year-old DJ slowly - is now said to be desperately trying to find time to see him before she jets off on her 'The 1989 World Tour' at the beginning of summer. A source said: "Taylor wants to spend as much time as possible with Calvin before she leaves for her tour. So this month is all about Calvin."
The blonde beauty, 25 - whose past love interests include John Mayer, Harry Styles and Taylor Lautner - is said to be "smitten" with the 'Summer' hitmaker and he has already received the thumbs up from Taylor's close pals.
The insider told HollywoodLife.com: "They're aware he's treated Taylor great so far, she's told them glowing things about how well-mannered he is towards her, so they think Calvin could be perfect for her.
"He's also been a bit of a player in the past - but he wants to do the right thing by Taylor."
It is thought Calvin first began to woo Taylor by texting her after the pair crossed paths at the BRIT Awards last month.
A source close to the 25-year-old signer said: "That's when it really started popping off."
The couple were recently spotted strolling around Taylor's native Nashville, Tennessee, before attending Kenny Chesney's concert together and Calvin is said to have made no attempt to hide his affections for the star.
A source said: "He wrapped his arms around her and kissed her."
