“The ring is rose-cut diamonds set in rose gold,” a friend told OK! “ It’s a very feminine piece of jewelry and very old.” 

So, did anyone see him buy it?  No, it was bought through a friend who specializes in estate sales, according to OK! 

“The diamonds aren’t huge, and it doesn’t look like an engagement ring,” the friend said. “ Rob is more mature than Kristen and he’s ready to settle down.” 

Hmmm…we’re not buying it.  OK!  magazine isn’t exactly known for its journalistic integrity. 

One thing we do know: RPatz isn’t exactly the picture of sexy in the bedroom, according to his Water for Elephants co-star, Reese Witherspoon. 

“Rob possibly had the most hideous, horrible cold of any co-star I’ve ever had to do a love scene with ever in my entire life,” Witherspoon revealed recently. “ He was literally snorting and snotting through every second of it — and it was not appealing.  I’m talking green, infectious, disgusting — I’m not kidding!” 

Ewwww.  We can’t blame the guy though — everyone gets sick!  She also said the British hottie was a dirty, dirty boy. 

“Well, it’s a boy thing, right?  To have dirty fingernails and dirty hair, and his clothes were dirty all the time,” Witherspoon said when asked about Pattinson’s personal hygiene. 

No love lost, though — Pattinson said that his favorite co-star during filming was the elephant. 

“I think I had a relationship with the elephant, [but] it was kind of based purely on candy,” he said last month at WonderCon. “ I strategically placed mints, like, [I] suck[ed] on a peppermint for a bit and then stick it onto [my] body, like into my armpits…and [I didn’t] tell anyone.  So every single time the elephant would be constantly sniffing me, and I’d be like, ‘I don’t know, she just really likes me, it’s crazy!’  But yeah, I think she was just sniffing around for a treat.” 

Um…okay.  Here’s hoping he took out the peppermint before the love scenes.
