"It was mutual decision," the insider tells Us of the Harry Potter actress, 24, and Oxford University stud, 22, who first took their relationship public this past January. The good-looking pair were photographed together during an affectionate getaway in the Caribbean.
Janney's "second mother" Coralie Day — who took him in after his parents passed away — told the UK's Evening Standard that same month that she was "thrilled" with the pairing. The two were rarely photographed together after their PDA-filled vacation, but Janney occasionally joined his famous girlfriend on press trips abroad.
Though the exact timeline of their split remains unknown, the two have been busier than ever after breakup. The insider tells Us that the actress has "moved on and is currently busy with work and her lining up some philanthropic pushes."
A spokesperson for Watson told the Daily Mail, which first reported the story on Friday, Dec. 12, that the split was "amicable."
Indeed, Watson is currently filming her upcoming drama, Colonia Dignidad, in Argentina and Germany. The film, which is based on a true story, tells the tale of a German wife (Watson) searching for her kidnapped husband in 1973 under the dictatorship Chilean dictator General Augusto Pinochet. The film also stars Daniel Bruhl and Michael Nyqvist. She also made headlines after delivering a powerful speech at the U.N. this past September, further discussing her "He for She" gender equality foundation.
Janney, meanwhile, continues to play for Oxford's rugby team, helping his teammates to victory against Cambridge on Thursday, Dec. 11.
Prior to Janney, Watson was in a long-term relationship with her Brown University sweetheart Will Adamowicz, whom she dated from spring 2012 to summer 2013.
Watson and another megastar Brit Harry Styles recently had fans swooning after the One Direction heartthrob presented her with an award at the British Fashion Awards in London in early December. Still, the source tells Us that Hemma is out of the question.
"She has no plans to date Harry Styles," the insider says, "though he was nice at the awards."
