At the beginning of season four, Amy and Ricky are together and are trying to be a real family for their son.After the stillborn death of Ben and Adrian's daughter, Amy and Ricky begin a sexual relationship.
At a graduation party, Ricky kisses Adrian one last time; something Amy allowed.
Not knowing this at first, Amy thinks that Jimmy broke up with her because she was a bad kisser, and asks Ricky to kiss her just to be sure.
Adrian finds out about the kiss, and sleeps with Ben in order to get back at both of them (however, Adrian believed it was more than a kiss until Ricky informs her after Adrian and Ben's one-night-stand.) Amy and Ben quickly reconcile and get back together around the end of the year.
Amy then decides on adoption, and discovers that her father's longtime employee Donovan and his husband Leon want to adopt the baby.
The adoption fails due to Ricky's interference, and she ultimately decides to keep the baby due to the love and support of her family and friends.She confesses her pregnancy to her two best friends, Madison and Lauren, who accidentally spread the rumor that Amy had sex with Ricky.
