Her little sister is getting married, but the wedding day is going to prove to be a difficult one for Brooke (Katherine Kelly Lang) on The Bold and the Beautiful.

Katie Asks Brooke For A Big Favor

Katie (Heather Tom) and Bill's (Don Diamont) first marriage fell apart after he and Brooke started to see one another, but Brooke and Bill's romance came to an end after Brooke left for Italy and encouraged him to reunite with Katie. Now, not only is the fact that Katie and Bill are getting married again rough for her, but she is also forced to be even more supportive because she is Katie's matron of honor-and it is all making things more difficult for her.

And though the focus should be on Katie and Bill, her possibly reacting negatively could shift a lot of attention to her instead-including from Bill, who will check to make sure she is okay with watching him profess his love to her sister once again.

Brooke Forced To Be Alone After Ridge's Rejection

"Everything's turned out the way it should be," she says to Bill in a preview clip for the Tuesday, Feb. 17 episode.

However, Bill won't be the only one who is concerned about Brooke's state of mind, as Donna (Jennifer Gareis) will also try to make sure that Brooke can handle the day's events.

"You are sure then that this is what you want?" she asks Brooke in the clip.

However, as concern for her grows, it could mean good things for Brooke, who descended into drinking excessively after she failed to get Ridge (Thorsten Kaye) back from Caroline (Linsey Godfrey). Among those concerned for her well-being during the wedding is none other than Ridge himself.

"Logan is Katie's matron of honor. It's going to be a difficult day for her," he says in the clip.

The Bold and the Beautiful airs Monday-Friday at 1:30 p.m. on CBS.
