Jake Gyllenhaal vacations in Italy with a 'longtime best friend'Rome, May 31 (AZINS) Actor Jake Gyllenhaal, who is still sporting the muscle he amassed for his role in "Southpaw", was spotted in Italy while on vacation with his friend Greta Caruso.

Wearing just shorts and bushy beard, the star was seen relaxing by the pool in Amalfi, Italy, reports people.com.

To get in shape for his role in the boxing flick, Gyllenhaal followed an extreme workout schedule - including 1,000 sit-ups a day, 100 pull-ups, 100 dips, two sets of 100 squats, jumping rope and running eight miles a day.

Accompanied by Caruso, who a source confirms is Gyllenhaal's "longtime best friend", the actor was taking some much-deserved time off after wrapping his next film "Everest".

Caruso, 31, is the daughter of "CSI: Miami" actor David Caruso and his second wife Rachel Ticotin.
