Brittny Gastineau and Kim Kardashian
from NFL star Reggie Bush surprised even her own BFF, reality TV star Brittny Gastineau.
"I loved them as a couple," Gastineau, who appears regularly alongside Kardashian in the E! reality series Keeping Up with The Kardashians
, told PEOPLE Tuesday afternoon. "I thought they were great. I always said that they were the same person. I never met a couple who were so great. They clicked well together."
So what prompted the pair to call it quits? "They're both just so busy, and their schedules are so hectic," according to Gastineau.
And thanks to Kardashian's busy schedule, she can keep her mind off her personal woes: "Kim's okay," says Gastineau. "She's a very strong woman. She's very focused and smart. She'll be totally fine. But I hate to see anyone split. She's my best friend, so I hate to see my best friend sad."
Gastineau, who has a cameo in the new film Brüno
, says the exes remain on friendly terms. "They love each other so much, they're best friends, but whatever is meant to happen, happens."
So is it feasible that Kardashian, 28, and Bush, 24, could one day get back together? "Who knows what's going to happen in the future," says Gastineau. "Anything is possible."
Gastineau, who's single herself, says her pal need not worry about being unattached. She said, laughing, "It's not that bad! She'll be fine. I think we'll be doing a lot of movie nights!"
