In addition to breaking the hearts of delusional Maroon 5 and 'The Voice' fans everywhere, Adam Levine broke another heart when he announced his out-of-the-blue engagement to model Behati Prinsloo.

Yet another swimsuit model, Nina Agdal, was devastated by the news.

Levine dated well-documented sweetheart Agdal briefly after his split from Prinsloo, with initial reports of their relationship emerging towards the end of May of this year. They certainly appeared to have fun together, no?

A source told Page Six that Agdal is "heartbroken" over the news of Levine and Prinsloo's reunion, which she learned about via a text from the tattooed rocker.

Cold, Levine!

What's worse? Radar Online says he broke the news merely a week after vacationing with Agdal in Las Vegas.

Somehow, though, we don't think she'll have a hard time moving on. And if this is Levine's M.O., frankly, Agdal may have dodged a bullet.
