Fans watched Jessica and Alex clash in the Big Brother house this season, first over their bonds with Cody Nickson and then over a desire for power.
When Jessica finally got evicted from the house last week after putting up a great fight, Alex had some choice words for her.
"Hey, Jessica, I just wanted to say thank you for hating me for absolutely no reason and trying to get me evicted multiple times," Alex said in a pre-taped farewell video that Big Brother host Julie Chen played after interviewing Jessica live onstage.
"I want to wish you a great summer not going to jury. And PS, don't worry about Cody -- I'll watch him for you."
And Jessica did not appreciate the message at all, especially since Cody is officially Jessica's boyfriend and she couple has said, "I love you," to one another.
"Her goodbye message was disgusting," Jessica, 26, told Us Weekly of Alex, 28. "I don't condone that behavior and it just shows the kind of person she really is. And her goodbye message just reiterates everything I thought about her."
Alex and Cody were very close at the beginning of the Big Brother game because the former Marine really respected her as a physical player.
At one point, Cody -- who claims he never cries -- almost shed tears over the idea of losing Alex from the house, and he has said in recent days he would never target her.
With that being said, Alex's pawns on the chopping block this week are Elena Davies, Jason Dent and Matt Clines heading into Wednesday night's Power of Veto competition.
"I was never a fan of Alex because she never stayed loyal to Cody after he saved her and Jason when he was HOH," Jessica recalled to the magazine.

"I think that Alex is a fierce competitor and I respect that. She definitely put a lot of fear in a lot of people in the house. However, her relationship with Jason is just weird to me."
Alex was previously shown telling cameras that she didn't understand why Jessica disliked her. But aside from the fact viewers suspected Jessica was jealous of Alex's relationship with Cody, the two women battled it out over a fashion accessory.
"I actually wore cat ears on the second day and Alex was like, 'I brought them too!'" Jessica revealed. "So I figured I couldn't wear them again -- she would hijack my style."
