Did Spencer Pratt give Whitney Port the crystal bug?

They say diamonds are a girl's best friend, but lately, trendsetter Whitney Port has got eyes for a different type of gem. The former "City" lead, who's now back in sunny Los Angeles, tweeted earlier this week that she's got a new obsession: crystals! Sound a little familiar? As you may recall, Whit's "Hills" co-star, Spencer Pratt, was (and still is) an intense aficionado of crystals, and when he and wife Heidi Montag spotted Whit's tweet (and accompanying Intagram pic, shown above), they felt an immediate connection to their long-lost friend. Could a reunion be far behind?

Elsewhere on Twitter this week, Holland Roden gave a nod to Dr. Deaton's "Teen Wolf" expertise, but Nicole Byer of "Girl Code" proudly shared a novice moment. And though Jenna said she and Lauren bonded on "Real World: Ex-Plosion" over the evening's pregnancy shocker, Jacy explained why she and John were separated on their "Are You the One?" date.

Below, see what some of MTV's best and brightest had to say on Twitter this week, plus catch a classic "Hills" moment featuring Spence and his crystals.
