It was another jam-packed episode of 90210 Tuesday, with four shocking revelations for the beautiful people of Beverly Hills.

First: Adriana is pregnant! At a support group with her sponsor, Kelly (Jennie Garth) and Brenda (Shannen Doherty) by her side, recovering addict Adrianna (Jessica Lowndes) learned that her friend, who she slept with a “couple times,” contracted HIV and relapsed. Brenda and Kellie insisted she get herself tested and accompanied her to a clinic. There, Adriana found out that she’s HIV-negative — but she was pregnant! After plenty of tears, she called Navid (Michael Steger).

Second: Brenda can’t have kids! At the clinic, Brenda freaked out when she heard that Adrianna was pregnant and ran out. Later, Kelly confronted her and Brenda revealed that she had complications with her thyroid problem and will not be able to have children of her own. “I’m pathetic. I’m jealous of a 16-year-old girl,” she explained about why she left suddenly. But then she revealed that she wanted to adopt.

Third: Sean is an imposter! Annie (Shenae Grimes) overheard her new brother on the phone talking about the money and asked him about it. Sean (Josh Henderson) told the family that his adoptive father got into serious gambling debt and committed suicide. Now Sean owed mean people money. Harry (Rob Estes) was ready to borrow against his 401K or use his kids’ college funds. But Annie and her mom confronted Harry and told him they didn’t trust Sean. When Harry asked him to take a paternity test, he said he would, but slipped out during the night instead. However, stopped by his “mother’s” home and scammed Naomi (AnnaLynne McCord) and her mom out of $200,000 before skipping town.

Fourth: Christina is a bisexual cheerleader! Dixon (Tristan Wilds) accompanied his friend Christina (Lauren London) to a gospel event at her father’s home. He was happy to be around other African-Americans from Beverly Hills but felt uncomfortable when she invited him to dinner. He told her he has a girlfriend and Christina revealed that she did too and she wasn’t hitting on him, just being friendly. Then, he sang “Amazing Grace.”
