Robert Pattinson and FKA twigs have "great energy."
The 29-year-old actor, who started dating the 'Two Weeks' hitmaker last September and got engaged in April, is reportedly having the time of his life with the British beauty.
A source close to the 'Rover' star said: "They are very cute together and have great energy, Rob seems very happy. FKA seems to be a great fit for Rob. [They] seem to enjoy the same things."
The former 'Twilight Saga' star and the 27-year-old singer, who are currently living in his Beverly Hills home, work out together with celebrity trainer Harley Pasternak "almost daily" and "enjoy walks around Venice Beach."
The insider told PEOPLE.com: "[They are] generally very active [and] both seem to enjoy staying fit."
The duo, who were spotted attending an event to benefit earthquake victims in Nepal last week, are also "involved with charities" together.
But they also enjoy "quiet nights with friends and often have people over for dinner at Rob's."
Robert previously dated his co-star Kristen Stewart for three years until May, 2013.
The former couple split after failing to get past the 25-year-old actress' fling with director Rupert Sanders in July 2012.
