Nikki Reed was seen wearing two diamond rings nonchalantly on her right ring finger on the Golden Globes red carpet, marking her and boyfriend Ian Somerhalder's first celeb appearance as a couple. But everyone is wondering one thing: is it an engagement ring? Some say the "Vampire Diaries" star popped the question during the holidays, Hollywood Life reported on Wednesday.

Nikki, 26, has only been divorced for a month, but word on the street is that the "Twilight" actress is already engaged to 36-year-old Ian. As for why they haven't made their big announcement yet - apparently the vampire couple wants to keep it low-key for now.

"Nikki said she wears the ring on her right hand because they want to keep it quiet for now. They mentioned a June date, they are really excited," a source said.

The couple was spotted looking at rings and jewelry at the New Stone Age on Jan. 4. Ian and Nikki were said to have checked out 14K and 18K diamond rings.

"They were absolutely adorable and you could tell they are very much in love," a source said.

Things between Nikki and Ian have heated up since she announced her split from "American Idol" star Paul McDonald six months ago. The couple's divorce was finalized on Dec. 26 after they married one another only seven months after they began dating, The Mirror reported.

Notably, Ian had a previous relationship with his co-star, Nina Dobrev, who was also a good friend of Nikki's.
