Season 4 of "Real Housewives of Beverly Hills" ended with Lisa Vanderpump and Brandi Glanville very clearly hating each other.

However, Brandi was recently spotted at Lisa's new lounge, PUMP, causing speculation that the two may have made up before the return of season 5.

Rumors have reportedly begun suggesting that the Lisa and Brandi feud may have purely been for the cameras of RHOBH and the ratings.

A source for Radar Online has denied that the feud has ended.

"Brandi was having a night out with Kyle Richards and Camille Grammer. The plan was to go to The Abbey, but since PUMP is almost right next door they popped in there first to say hi," an insider told the website.

The source continued, "Make no mistake the feud between Brandi and Lisa is still going forward full force, but neither wanted to cause a scene on Friday night so they just exchanged quick hellos."

Although Kyle Richards made a point not to attend Vanderpump's restaurant opening, she posted a picture of the three women visiting PUMP with the caption, "Who ever thought this could happen?. . . Bygones be bygones."

"Once they arrived at The Abbey, Kyle told people there that the three had just popped into Lisa's place to show their support," a second source told Radar.

Two members of the RHOBH cast, Carlton Gebbia and Joyce Giraud, have already been fired, but it has reportedly been confirmed that Lisa will be returning for season 5.

There have been reports that Brandi will be returning for the upcoming season of the reality television show as well, according to buddytv.

"Brandi will absolutely be back for another season. There were rumors that she didn't want to do it anymore, or that certain cast members were vying to get her off the show, but she really loved doing it and will return," stated a source.
