"I love Kourtney and I love Travis, they're both amazing people and I wish them the best. They're so cute," she told the outlet.
While Rae seems to be the closest to Kourtney, she said that the whole Kardashian family welcomed her with open arms.
"She just gave me great advice," Addison said about Kim. "I think the entire family has always been so sweet to me and so loving and caring, just giving me advice on how to keep my spirits up especially in the tough times that come with, you know, kind of being under pressure in the spotlight sometimes. But they're all amazing, I love the Kardashian family so much."
With Keeping up with the Kardashians coming to an end — Rae even makes appearances in the final season — the TikToker is unsure if a reality show of her own is in her future.
"I feel like reality is a tough world to get into, so I'm not rushing into anything, but who knows? Maybe one day," she admitted.
While Kourtney and Travis have been friends for several years now, they were first suspected to be an item in January when they were spotted in Palm Springs together. They then confirmed their romance on social media on Valentine's Day.
Kourtney thinks "that Travis is the man she's going to share her dreams with," a pal told OK! while another insider spilled that Barker has "been telling everyone he's hit the jackpot with Kourtney."
The Blink-182 drummer is even said to be looking at engagement rings. "He's planning an ultra-romantic proposal," an insider explained. "He's still looking for the perfect ring, but that doesn't mean the baby-making has to wait until it's on her finger."
"It never felt right for them to date or hook up until now, mainly because they were scared it might mess up their friendship," a source previously told OK! about why their romance only blossomed now. "But the chemistry has always been there. And finally, they've decided to give this a go, have as much fun as possible and see where it takes them."
Since making it official, the pair have been sharing steamy PDA pics on social media, and Kourtney even tattooed "I love you" onto her man — after he got her name inked on his chest.
