Actors Robert Pattinson and Kristen Stewart may be planning to tie the knot secretly in summer.



"Robert Pattinson quietly proposed when they spent a couple of days on the Isle of Wight over New Year," dailystar.co.uk quoted a source as saying.

"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," the source said.

"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 source added.

The two met on the sets of "Twilight", which first came in 2008.
