Stephanie Pratt feels like a brother-less child.
The Hills star told UsMagazine.com that her sibling Spencer Pratt and his wife Heidi Montag "have not spoken to me since, like, September."
"It's really hard for me," Pratt, 23, told Us at last Wednesday's Hollywood premiere of Clash of the Titans. "I don't know what's going on with them at all. All I hear are the same rumors you guys are hearing. It sucks and it's embarrassing to have to ask other people what's going on."
During an interview with Fancast, Pratt added: "They've decided they don’t want me in their life...I'm kind of mourning the loss of him."
And she's not the only one shut out: "He cut a lot of his friends out," she told Fancast. "I don't know what's going on with him."
Montag debunked breakup rumors to Ryan Seacrest on Monday. "After everything we've been through -- it's a lot for any couple to go through -- everything's better now," she assured Seacrest. The couple may move "to Costa Rica or somewhere in Latin America," she added. "I think we're gonna go there and figure it out."
She also addressed talk of her husband's spat with producers of The Hills. "They said some really inappropriate things that I'm not really allowed to say," she explained vaguely. "Very inappropriate. Very out of line."
The Hills' final season begins on April 27.
