It's going to be an interesting summer for Speidi.

Following reports of Heidi and Spencer Pratt split, Jennifer Bunney tells that Heidi is ditching her husband this summer to live with her.

"She's moving in with me," said Bunney, a one-time featured star of The Hills, who clashed with Lauren Conrad over a boy. "They're not divorced." She said that the couple, who wed last April, are "going through some issues...I don't think you move in with your friend if your marriage is completely cruising along. If things are great, you don't move out and move in with your friend."

On Friday, Heidi's rep told TMZ that she is "looking to move out due to all the fake bad press that Spencer controls...She's tired of it and is looking for a place and wants to focus on her acting career."

On Sunday, Heidi Tweeted "So happy to finally spend time with my Bunny again!...Having a girls night sleepover with [Bunney]!!!"

Oh, yeah: all of this is for an apparent reality show, Bunney, 24, told Us Sunday. "The show will depict who we really are, without the producers trying to create situations. We want it to be, different from the Hills."

Bunney, an aspiring doctor in a long-distance relationship, explained the series will capture "huge turning points" in their lives. "Is [Heidi] going to be a single, independent woman or is she going to stay with Spencer?... We know fame is fleeting, fame is not going to support us for the rest of our lives. We need to make smart decisions right now."

How is volatile Spencer, 26, dealing with all of this? "I will probably know more about that when I go up today and spend some time with him," Bunney said. "I think that will be a big aspect of the show. How he handles it. I think he's laying low."

Many details for the show still need to be hashed out, Bunney said. "We've haven't found a house yet," Bunney explained Sunday. "We're looking today." And filming won't start until July, when Bunney is back from a family trip to Hong Kong.

MTV, which produces and broadcasts The Hills, confirmed to Us that it's not involved in Heidi's new show.
