The competition heats up between Neesee and Tia, who try to out-do each other by planning separate birthday parties for Bobby Jr., so Robert attempts to increase the peace between the women and bring everyone together for one big birthday bash.

When Robert invites Tia to move into his closet space, she gets jealous when she discovers his old wedding video showing a happy Robert with his now ex-wife Neesee. Meanwhile, a misunderstanding about which videotape Tia actually found gives Neesee leverage in a battle with Robert over who gets custody of Bobby's Jr.'s old crib.

Tia finds that she can't escape Robert's ex-wife, Neesee, even in her own workplace, when Neesee volunteers to be the school's newest kindergarten ""room mom"" and forms an instant bond with Tia's best friend, Jonelle. Meanwhile, R&B sensation and movie star Beyoncé Knowles turns the tables on Robert during an interview when she starts asking him personal questions.

After Tia uses Neesee's maiden name when forging her signature on one of Bobby Jr.'s permission slips, Neesee reveals that she intends to keep Robert's last name even though they're officially divorced.

When Neesee begins dating a handsome dentist, Robert becomes jealous, but claims his concern is for Bobby Jr.

When the station does a profile on Robert's home life, he insists that both Tia and Neesee be included, but when Neesee is edited out of the version that airs, the kids at Bobby's Jr.'s school joke that Neesee must be the nanny. Meanwhile, Neesee retaliates by filing a complaint that Tia and Robert's relationship is in violation of the rule against teachers dating students' parents.

Tia moves into the house with Robert only to discover that Bobby Jr. doesn't want her there, so when Robert and Dirk fail at making Bobby Jr. feel more comfortable with the new living arrangements, it's up to Neesee to try and help her son adjust. Meanwhile, Jonelle sublets Tia's old apartment and becomes friends with the neighbors who did not like Tia.

When Jonny, a recently divorced college friend of Robert, Dirk and Neesee's, comes to town, sparks fly after he and Neesee share a kiss, but Robert isn't happy to learn that Jonny and Neesee want to take things to the next level.

Now that they're living together, Robert and Tia worry that Bobby Jr. may have actually witnessed them having sex, and to make matters worse, they believe that Bobby Jr. has drawn a picture of what he saw and fear that he may show it to his Neesee.

Bobby Jr. catches his dad, who's decked out like St. Nick, in a kiss with Tia---and comes away believing his dad is the real Santa. Also, Tia's relationship with her visiting dad becomes strained.

Neesee contemplates quitting her burgeoning catering career when Bobby Jr. begins to act out both at home and at the TV station. Meanwhile, Dirk is surprised when he falls not for a sexy superstar, but for her lawyer.
