TORN-UP TAYLOR KEEPS TABS ON JOE

Secretly spies on one that got away

TAYLOR SWIFT is supposedly over the moon with new guy Matty Healy, but that hasn't stopped the dumped songbird from being nosy about the ex-lover who bruised her heart, actor Joe Alwyn.

Sources tell The National ENQUIRER the 33-year-old pop superstar is still feeling the sting after being given the heave-ho by the English hunk, 32, and wants to know what he's up to all the time - which people around her find baffling since Taylor didn't waste a sec jumping back on the dating-go-round.
