Ben Flajnik will be choosing his potential partner for the show's 16th edition, after appearing in The Bachelorette earlier this year.
The 29-year-old winemaker from Sonoma will be picking between the likes of Erika, a 23-year-old law student, "germ conscious" epidemiologist Emily - who steals this season's first kiss and performs a rap - and personal trainer Elyse, who makes him do pushups on the first night.
He will also be introduced to a "sprite senior citizen" who confesses that she is "madly in love with him" at the first cocktail party, while another bachelorette makes her entrance on horseback.
Another woman is said to dissolve into "uncontrollable tears" at the party.
Flajknik previously revealed that he is ready to find love again".
He appeared on the last season of The Bachelorette, where he proposed to Ashley Hebert in the season finale, but was turned down when she decided to accept a proposal from JP Rosenbaum instead.
