Last week rumors swirled as to whether or not Robert Pattinson purchased a $1 million Parisan home for girlfriend and Twilight co-star Kristen Stewart. Though these reports have yet to be confirmed, the couple is known for purchasing extravagant gifts for one another. For instance, on K-Stews 21st birthday, R-Patz presented her with a motorcycle. This past holiday, Stewart returned the favor by dropping $12,000 on vintage guitars for her man. Now it seems the Snow Whit and the Huntsman actress has splurged on instruments yet again!

Stewart has allegedly purchased a $79,000 piano for Pattinson, who was a struggling musician before scoring the coveted role of Edward Cullen in Twilight. So what's the reason for the gift? It just so happens that Robsten are celebrating their third anniversary. According to MTV:

Kristen wanted to get a huge surprise for Rob for their anniversary later this month. Robert's been playing the piano his whole life and admits it's the perfect escape for him when the showbiz world, paparazzi and fans get too much. Playing the piano is Rob's therapy when he needs to be alone, to think, to get emotional and creative.

The pair began dating after completing production on the second film in the Twilight series, New Moon. Since then, fans of the franchise have obsessed over their every move. This includes their recent trip to Paris and Pattinson's purchase of a $6 million L.A home. Their film Breaking Dawn: Part 2 is set to it theaters on November 16th.
