R-Pattz Gives K-Stew Grandmother's Ring

Robert Pattinson has allegedly cemented his romance withKristen Stewart by giving the actress his grandmother's ring.

According to Twilight hunk gave K-Stew the family heirloom on her 23rd birthday last Tuesday (April 9).

A source told the publication: "Rob gave Kristen his grandmother's treasured pearl ring.

"He just casually wrapped it in tissue, put it in an envelope and slipped it into her mailbox. No note, no words, just the ring. It was a huge statement on Rob's part symbolising his full forgiveness of Kristen and his renewed trust in her future."

Rob is also rumoured to have brought Kristen a £30,000 limited edition Bentley fountain pen for her b'day, with the insider adding: "There was the latest chain and bracelet set from Versace, and a Hermès silk scarf.

"He also managed to get hold of an original vinyl copy of her favourite Van Morrison song, 'Madame George'."

The couple were recently spotted holding hands at Coachella in California, where Stewart is said to have become upset after bumping into former fling Rupert Sanders' ex-wife, Liberty Ross.
