The 24-year-old British actor proposed to Stewart in the New Year and the couple are now planning to tie the knot soon, reported a website.
“Robert Pattinson quietly proposed when they spent a couple of days on the Isle of Wight over New Year.
“They don’t want to announce anything until they’ve finished filming the last Twilight film, but they’ve already contacted a wedding planner in California and are looking to have a small, intimate ceremony in Napa Valley,” said a source.
“They love the beauty of the area and are totally up for a hippie, earthy vibe. There’s no way they’d have a silver-plated blowout affair.”
The pair, who have never confirmed their relationship despite being spotted together on several occasions, is currently busy filming the second part of ‘The Twilight Saga: Breaking Dawn’.
