'The Bachelor' preview: Peter's date with Victoria F. is interrupted by her ex

There have been a few awkward moments on "The Bachelor" so far, but perhaps none will top this week's one-on-one between Peter Weber and Victoria F.'In an exclusive sneak peek of the date that Victoria gushed was "the best," Peter surprised her with a private concert.

However, she's shocked to discover that the frontman for the band is her ex-boyfriend.

"Nothing could be worse. I'm freaking out right now," she said. "The situation is so uncomfortable. I want to die."

When pressed about how she's going to tell Peter, she bursts into tears.

To see what happens, watch "The Bachelor" Monday at 8 p.m. ET/PT on ABC.
