Stephen Colletti Talks Kristin's Engagement

On Tuesday, the world learned that former Hills man-eater Kristin Cavallari is ready to settle down, after it was announced that the reality starlet became engaged to footballer Jay Cutler. During her time on both MTV's Laguna Beach and The Hills, the SoCal small-screen star fell in and out of love with Justin Bobby, Brody Jenner and Stephen Colletti, just to name a few.

And now one of those former paramours is offering his congratulations to the newly engaged actress. "I'm extremely happy for her," Colletti told Hollywood Life. "She deserves to be happy. She's getting engaged! It's weird. We're at that age now ... it's that reality check."

Colletti himself is currently dating Dancing With the Stars contestant Chelsea Kane, but he doesn't feel the need to put a ring on it just yet. "That's not something [that's on my mind right now]," he said. "Of course I'd like to get married someday though!"

Many of Cavallari's other former co-stars have remained mum on the subject, but former star of The City Whitney Port sent her love and support on Twitter. "@KristinCav heard from a little birdie the big news!" she wrote. "So happy for you, much love!!! Xoxo."

Cavallari has not directly commented on her engagement, but she did tweet her fans on Tuesday, writing, "My phone has not stopped today. Need to put it down."

Whitney Port Dyes Her Hair Red!

Lauren Conrad isn't the only Hills alum to make a major hair change. Whitney Port showed off a new reddish color at the Night of a Billion Stars party in L.A. on Thursday.

So what prompted the 25-year-old to dye her long blonde locks? "We changed just because we can! That's what hair color is all about," the star's hair pro, Kristin Ess told Us Magazine of the color she jokingly calls "apricot gingersnap."

To get the desired effect, Ess first applied an apricot base, followed by a matching gloss to add shine and help lock in the new color. Then, she topped it off with a few fine blonde highlights around Port’s face and at the ends so it looks natural.

"Whitney loves it. She's already feeling comfortable [as a redhead] and that's most important," says Ess.
