Since Nikki Reed's NYC performance with her ex-husband Paul McDonald on Thursday, tabloids have been suggesting that Reed and McDonald might also reunite for another chance at romance.

Perez Hilton reports that after their performance at Bloomingdale's on Thursday, Reed and McDonald stood close and posed for pictures at Bloomingdale's Pink Party.

Despite their divorce, Reed and McDonald remain friends and continue to sing and work together, Inquistr reports.

Because of her working relationship and friendship with her ex, Reed's current boyfriend, Ian Somerhalder is beginning to get jealous, says Celebrity Dirty Laundry.

"[Ian's] having a hard time trusting that nothing romantic is going on," claims the Celebrity Dirty Laundry source.

The Inquistr also adds that Somerhalder's jealousy quickly turned into him having an overly clingy attitude that has now caused Reed to "slow things down" with the "Vampire Diaries" actor and focus on her working relationship with her ex husband.

News of Reed and Somerhalder's relationship first surfaced back in July. Since then, Somerhalder and Reed have been reportedly "inseparable," claims Cambio.

Somerhalder even took to Instagram to defend his and Reed's romance after his "Vampire Diaries" fans slammed Reed for being Somerhalder's new girlfriend, E! News reports.

Last month, one of Somerhalder's fans took to Instagram to post a disparaging comment about Reed underneath one of Somerhalder's photos. Following the user's nasty comment, Somerhalder responded with a comment of his own, claims E! News.

"You HATE NIKKI REED? Really? Do you know her? Hmmmm, I'm not sure that you do. Look on her Instagram feed or twitter and all you will see is a compassionate and beautiful human being," Somerhalder,, wrote. "Please put your negative energy elsewhere. You don't even know the person you're talking about."

Check out the Instagram photo that first started Somerhalder's rant below.
