Nina Dobrev 'Disses' Ian Somerhalder & Nikki Reed Romance? 'Vampire Diaries' Beauty Shares Cryptic Instagram Poem, Jealous of Ex-Boyfriend?

Rumors suggest that Ian Somerhalder is currently dating stunning "Twilight" actress, Nikki Reed. And apparently, Somerhalder's ex-girlfriend Nina Dobrev isn't pleased.

Things are definitely heating-up between the former Christian Grey-favorite and 26-year-old Reed. Check out some photos of the two Hollywood stars "cuddling-up" at a local farmer's market in LA.

The "new" couple hope to keep their blossoming romance on the "down low" - which is why Dobrev had no idea that her ex-beau had officially moved-on! According to an alleged HollywoodLife.com insider:

"Ian and Nikki are still in the trial stage of their relationship and they haven't shared with many that they are testing it out. They don't ever want to broadcast to the world what they are doing in their personal life, especially if it isn't going to go anywhere... They are definitely keeping others [Nina & Paul McDonald's] feelings close as they work on their decisions to start an exclusive relationship together. They don't want to upset anyone. It is beyond baby steps right now between the two and Nina hasn't been told anything. But Nina isn't stupid either, she reads the gossip like the rest of us so she will know soon enough."

Apparently, that time has come...

The "Vampire Diares" cutie recently posted these rather cryptic messages on Instagram:

ninadobrev: "#repost @sukiwaterhouse."

ninadobrev: "'A fool flatters himself, a wise man flatters the fool' #repost @eli_miz."

Although they broke-up months ago, is Dobrev jealous of her ex's new flame?
