Eight men get the surprise of their life as husband and wife actors Jason Biggs (“American Pie” movies, “Orange Is the New Black”) and Jenny Mollen (TV series “Angel” and “Crash”) take them to a birthing class with hilarious results. Which one of Hannah’s suitors will endure the experience of simulating childbirth? The Bachelorette gets a real-life health scare and one bachelor comes to her rescue. In return, she rewards him with a private concert by Danish pop and soul band Lukas Graham, performing their hit, “Love Someone.” Hannah brings another group of men on a professional photo shoot where they are shocked to find that they are posing with professional models—who are adorable animals. The curious Bachelorette once again employs Demi to share with her what the men do when she is not around, reminiscent of the new Illumination Entertainment film from the creators of “Despicable Me,” “The Secret Life of Pets 2.” Will the guys pass Demi’s test? And later, will one man spin out of control and out of Hannah’s life? The men battle to get a rose, whatever it takes.
