Harry Potter star Emma Watson has split from her long-term boyfriend.

Despite reports that the 23-year-old actress was on the brink of becoming engaged to millionaire’s son William Adamowicz, 23, friends say the couple have parted because of her hectic film schedule.

Emma – best known for her role as Hermoine Granger in the Harry Potter films – and Adamowicz met as students at Oxford in 2011.

They were last spotted together in November at the Shepherd’s Bush Empire in west London, watching acoustic folk rock trio The Staves.

Emma is coy when it comes to talking about the men in her life, although she has had several relationships since finding global stardom.

She claims she is no good at playing the dating game and has suggested that men are too scared by her “fame wall” to talk to her.

Last night her spokesman confirmed: “Emma and Will separated last summer and are no longer in touch.”
