The revved-up duo have been spending more time in coffee houses recently than the cast of Friends, getting their caffeine as they conduct their own little java tour.
They're showing no signs of slowing down, with the latest sighting on Tuesday when they stopped into the Frothy Monkey in Nashville around 10 a.m., their second trip to the shop – they were there on Sunday, also.
"Apparently Jake likes a cappuccino with maple syrup," says a source who saw him order the drink. "Frothy has the real deal in the maple syrup department."
On Monday, Swift, 20 and Gyllenhaal, 29 – who so far have been said to tip well – sampled cups of Joe at another Nashville shop called Crema.
On Saturday, the pair ducked into Fido, a coffeehouse and café near Vanderbilt University and Music Row.
Even the Thanksgiving holiday didn't dampen their need for a fix. There were more maple lattes on the menu at Gorilla Coffee in Brooklyn, N.Y., when the two stars popped in for specialty maple lattes made with pure Vermont syrup.
Then there was that fun-packed weekend in New York in October, when they brunched with another couple at Al Di La in Brooklyn and, says an onlooker, looked "friendly." It's probably a safe bet to say they both ordered … coffee.
