Latest on Heidi Montag & Spencer Pratt

This just in from BuddyTV.com, Spencer and Heidi are still together, but things aren't totally smoothed out.

According to the site, the couple is featured on the current issue of Life and Style magazine. From Buddy TV:

The two were down in Los Cabos, Mexico, earlier this month, reports Life and Style. But, the magazine says, the trip doesn't mean there's been any forward momentum after the big step back from their engagement.

An insider apparently told the magazine, “The wedding planning really broke up the engagement…Heidi isn't convinced Spencer understands the meaning of a lifelong commitment.”

The magazine also reports that the trip ended on a distinctly sour note, although not for any reasons related to the relationship woes. “I've been throwing up all night,” Heidi apparently said upon her return. “I just got back from Mexico. I don't know what I have; I don't know if it's food poisoning. I'm just so sick.”

The couple also attended the recent premiere for Cloverfield, but saw far on the other side of the theather, away from Hills stars Lauren Conrad and Audrina Partridge.
