John Mellencamp Has the Best Reaction to Teddi Mellencamp Arroyave on Celebrity Big Brother

Teddi Mellencamp Arroyave is officially living in the Celebrity Big Brother house, and her dad, John Mellencamp, is showing his support for his daughter's latest adventure — in the most hilarious way.

The Rock and Roll Hall of Famer cheered Teddi on as she entered the Celebrity Big Brother house in a post on Instagram on February 2, which included a photo of himself with his daughter and granddaughters Slate, 9, and Dove, who turns 2 later this month (Teddi previously shared the same photo on her Instagram, which you can check out, below). The post also featured a black-and-white throwback photo of John and Teddi when she was a kid.

But it was the caption to the post that will really bring a smile to your face. "A television show that Teddi is on premieres tonight," John wrote. "I don’t know what she’s doing, but I’m proud of her and hope she achieves her goals."

Thankfully, Teddi's husband, Edwin Arroyave, has a bit of a better idea of what Teddi will be getting up to on Celebrity Big Brother, and he's pretty confident that his wife could take home the $250,000 grand prize at the end of the season. "Tonight is the night! As I sit here trying to think of the words to write, I am honestly filled with excitement for my beautiful wife @teddimellencamp. I cannot begin to describe how proud I am to stand beside such an amazing woman," Edwin gushed on Instagram on February 2. "I may be biased, but I definitely think she stands as the top candidate for this season’s [Celebrity Big Brother winner]… am I right?"

Even though Edwin wants Teddi to stay in the Celebrity Big Brother house for as long as possible, he is, of course, missing his wife every day that she's away. "It’s crazy that it’s been TWO full weeks since you began this journey. Not to mention the longest time we have been away from each other, how am I surviving… lol. Trust me when I tell you, the kids (and of course, me) miss you so much. Nothing is better than hearing you waking up our Dovey with your infamous song we all have grown to love!" Edwin continued in his post. "I would wish you luck, but I know you don’t need it! You inspire me every single day through your pure determination, mental toughness, gentle heart and your compassion for others."

"We’re rooting for you!!" Edwin ended the post, which also had some love for Teddi in the comments section from Kyle Richards' eldest daughter, Farrah Aldjufrie, and Tamra Judge, who also hosted a Celebrity Big Brother premiere night party in support of her podcast co-host on the show.

Edwin also applauded Teddi for her "amazing" debut on Celebrity Big Brother in another Instagram post, noting how she almost won the first Head of Household competition of the season (former UFC champion Miesha Tate ended up winning HoH). "Hey, beautiful. We're so excited for you," Edwin shared in a video on Instagram on February 3, which also featured Slate and son Cruz, 7, wishing their mom "good luck." "Can't wait to see you compete, kick some butt, and do what you do best, which is win and inspire many, many people. We love you."

Kyle praised Teddi in the comments section of Edwin's post, writing, "She killed it!!!" She, along with the rest of The Real Housewives of Beverly Hills family, also sent their best wishes to Teddi in a video. "Good luck, Teddi! We love you so much. You're gonna kill it!" Kyle said in the clip, which also featured her fellow Beverly Hills Housewives and husband Mauricio Umansky cheering Teddi on while aboard a private jet. "Go out there and kill it and win it!"
