Riley Perrin is Ben's closest female friend and girlfriend. She also has a crush on him, though it is not to his knowledge. When Ben becomes a surprise father to a baby girl left on his doorstep by an ex-girlfriend, Riley helps raise the baby along with their friend Tucker, Ben's mother Bonnie and brother Danny. She is portrayed by Chelsea Kane.


Riley used to be the overweight girl next door who Ben and Danny would call "fatpants", but she has now blossomed into a beautiful young woman in law school. Riley's hopeful that Ben will finally take notice, but she doesn't realize that Ben's brother Danny is harboring a secret crush on her.[1]



Riley comes over to help Ben, Danny, and Tucker with Ben's new baby after she gets a call from Danny. Ben is surprised at her new look, having previously thought she still had a heavyset frame. She tells the guys she needed some items, so Ben and Tucker quickly leave. While they are gone, Danny finds out about her crush on Ben.

When she tries to leave after helping them, Danny blackmails her by using her crush on Ben. He tells Ben to tell her not to leave and Ben agrees and hugs Riley.

The next day, while hanging out, Danny asks her how long she had had a crush on Ben, but Riley doesn't know. He tells her she should move on since Ben had a baby. Riley thinks Ben could take care of Emma, but Danny counters, saying he had signed the adoption papers. Riley thinks it was only because no one believed he could do it since they all pushed for him to sign them.

She leaves to go help Ben with the baby since Bonnie was leaving. Before she can get to his door, Danny stops her and tells her to let him take care of her by himself or he'd never believe in himself and she agrees. When Tucker comes by, they stop him too and Ben is forced to change her diaper by himself. Danny, Riley, and Tucker eat and sleep out in the hall. The next day, Ben tells them he wanted to raise Emma.

I Told You So

Riley gets a text from Ben and goes to his job and asks him what the problem was. Ben loudly reprimands her before telling her that he wasn't allowed to bring Emma to work, so he told his boss that her mother was outside smoking. Riley shrugs it off and has a drink.

Ben gets a date and leaves Emma in Danny and Tucker's care. After calling them both, he realizes neither of them was with Emma and rushes home. Bonnie and Riley come and he sees that they have her and he tells Emma he never wanted her out of his sight again.

The Nurse and the Curse

Ben and Tucker take Emma to her first doctor's appointment and Ben ends up asking the nurse out on a date, much to Riley's jealousy. She does not believe someone could be so chipper all the time, but Ben manages to get her to befriend Cassie. At Danny's first game with the NY Rangers, Cassie tells Riley that she knew Riley had a crush on Ben, but Riley denies it. Cassie tells her she didn't see her as competition since to Ben, she would always be "Fat Pants" and Riley gets in a fight with her which is broadcasted on the jumbotron.

Guys, Interrupted

Ben urges Riley to go on a date with her study buddy.

Married to the Job

Take Her Out of the Ballgame

She is elected as the captain of Ben's softball team, but takes the game too serious.  The team members decide to kick her out of the position and reinstate Ben as the captain.  Riley finds out via text and storms out of Ben's balcony.  Riley and Ben make up after Ben visits her at the baseball field and says that he wants her to be part of his life and his team.
