It would not come as a surprise if Reed, 26, and Somerhalder, 35, were to take their relationship to the next level, especially as their love and devotion to each other is written all over Instagram.

The couple moved in together after only three weeks of dating. They settled for Atlanta, where Somerhalder films the CW series "The Vampire Diaries." The place became the perfect place to settle since an insider previously told Us Weekly that Nikki can go "see the set every day."

Not only have they moved in together, but the Hollywood actors have made not one, two, three or even four, but five additions to their family.  

Their animal family have begun since Us broke the news of the duo's relationship in July. They currently have horses named Eagle and Millie, and are parents to an unnamed kitten, as well as two adopted dogs.

"Went to the animal shelter today to give some love to the babies living in cages who don't have homes and ended up adopting this little girl!" Reed captioned on her Instagram pic Oct. 15 with their new cat. "What should we name her?"

On Oct. 28, the "TVD" and "Twilight" stars went horseback riding in Atlanta while Ian was on a break from filming the TV series. 

"A beautiful perfect Georgia afternoon decompressing from work with our big boy Eagle (who opted out of this photo), our little girl Millie (who you all haven't seen yet but here she is) & the one and only @iamnikkireed," captioned Somerhalder on his Instagram pic of the couple riding on their horses.

"Photographed by my lovely sista Kat Graham aka @katgrahampics. The simple beauty of the quiet countryside loving on my kids with these amazing women...Wow, love this," added the 35-year-old. "Needed this. So many amazing things happening with all of the projects in my life - thank you for so much love and support. Thank you."

Meanwhile, Nina Dobrev, 26, is reportedly still having a hard time dealing with her ex-boyfriend dating her former friend.

However, not only are they dating, have moved in together, and seemed to be bent on building a fur family together, a source revealed to HollywoodLife.com, that Ian sees his relationship with Nina as nothing compared to what he and Nikki has.

"His relationship with Nina was what it was - it lasted the amount of time it was meant to last - but with Nikki, he feels like he has found the one," according to the source.

"Ian is in love with Nikki and the life they have, and he wants to share his love because he is not ashamed of the greatness that his life is experiencing with her in it," added the source.

"If it comes off and looks like he is doing it to mess with Nina's head, it's not the case. He is 100% all in with Nikki and Nina is just an afterthought," explained the source of Ian's perspective on his relationship with Reed. "He wants the world to know Nikki is his girl and they are having a great time. There is no other drama-filled reason attached to it."

Nina has been spending her time with BFF Jessica Szohr, 29, these days.

"Jessica and Nina are together nonstop lately; they're getting super close," according reportedly told HollywoodLife.com. "She's friends with Nikki too so she's trying not to take sides."

"She's working on getting them to talk things out and make up but she's not pushing; she's definitely on Team Nina if it came down to that," the source added.
