Brooke Roberts is a woman who was "looking for a man" on The Bachelorette in "Brian the Bachelor". Her final choice comes down to Brian Griffin and Glenn Quagmire, eliminating such contestants as Frankenberry and Trevor. She chooses Brian, who she first bonded with during a horseback riding challenge. Brian had fallen in love with her by this time. She ended up leaving him as it was only intended to be just a television show and not a long-term relationship.
In "Valentine's Day in Quahog", Stewie gathers scores of Brian’s former girlfriends including Brooke to get to the bottom of why he’s unsuccessful in love. When Brian lashes back at the criticism, he notes that Brooke's vomit "tastes weird."
