On Monday's episode (airing Aug. 12) of The Bold and The Beautiful, everyone's relationships are falling apart -- and it's because of a third wheel.

The clip below starts out with Donna asking Brooke about her feelings toward Bill.

"What about your feelings for him?" Donna asks.

Brooke replies: "I'll just have to bury them. Bill and I are not going to act on our feelings for each other."

But, it turns out they do act on their feelings. On Friday's episode, we saw Brooke leaving for Monte Carlo, which was supposed to give Katie and Bill time to rekindle their romance. However, it turns out Brooke's trip only made Bill want her more.

Last week, Katie spied on Bill and Brooke via a hidden web camera. In the clip, we learn that Bill finds out about the surveillance equipment.

"He found the cameras," Katie says. "He knows I was spying on them."

This might have forced Bill to run away from Katie since he ends up surprising Brooke in along the French Riviera.

"I love you," he tells her. "I want to be with you."

Brooke, who first says, "This could never happen," caves in and kisses him back. We see them making out on top of a boat and flaunting their romance.

We also see Bill throwing his wedding ring into the ocean and saying, "Katie and I are finished." Can this mean his and Katie's marriage is officially over?

After Brooke tells Katie over the phone that Bill is in Monte Carlo, she shouts, "He's yours, you win!"

Meanwhile, Maya and Rick are having their own problems. In the clip we see Rick on the phone apologizing to Maya for being late to their date.

"I cannot believe that Rick did not show up tonight," Maya says.

However, once Maya starts drinking wine, it seems she forgets all about Rick and instead, turns to Carter for comfort...too much comfort. They start passionately kissing- which may or may not be the exact moment Rick shows up.

According to Soap She Knows, Caroline receives a huge favor. Can it be from her co-worker Rick and if so, does it have anything to do with Maya? Stay tuned for more spoilers!
