Over the weekend, “Saturday Night Live” aired its season finale, which saw platinum selling crooner Justin Timberlake take the reigns as the evening’s host, and fellow pop sensation Lady Gaga as the musical guest.  And we must say … these two pop megastars totally KILLED IT!

Some of the night’s highlights were:

Justin, Gaga and Andy Samberg in “Three-Way”: Gaga jumped in to help Justin and Andy continue their hilarious string of skits, which included “D— in a Box” and “Mother Lover,” for the “Three-Way” skit in which they explain the “Golden Rule” that a three-way with another guy is a “gray area.” (Fact!)

“Bring It Down” Part 2: JT’s 2009 “Bring It on Down to Plasticville” sketch, in which he wore a breast implant costume, was one of his most popular to date. And he took it to the next level Saturday night by dressing up as a beer bottle and singing odes to “Liquorville,” while Kristin Wiig sang in a teabag costume. Lady Gaga later comes out to help Justin … dressed in a wine bottle!

Gaga Baby: The singer performed hits like “Judas,” and “Edge of Glory,” then it was no surprise that she’d sing her mega hit “Born This Way” as her final number. What was surprising was that she came out with a pregnant belly partway through her performance, then gave birth onstage … to glitter!

#1: Why did Allure hide Jill Scott behind a bush, but left Gabrielle Union out in the field?

#2: Does Jermaine Dupri use a booster seat when he drives?

#3: Why is Madonna’s new album shitting on “Discipline” and it hasn’t even been released yet?

#4: Why is “Don’t talk to me, you know better than that!” [Jay-Z] so damn funny?

#5: Why did Wesley Snipes get 3 years in prison, and those racist ass cops who murdered a black man for no apparent reason didn’t spend one day behind bars? All Wesley did was not pay the government. Those idiots filled an un-armed person with 50 bullets! Am I the only one who feels this way?

#6: Why hasn’t Hillary Clinton just given up yet?

#7: Why is everyone surprised that Mariah Carey lip-synchs? I mean really, who doesn’t lip-synch every now and then?

#8: What the fuck is taking so long to get R. Kelly convicted?

#9: Why isn’t anyone calling out “shitty cent” on his bitchassness?

#10: Why is Khia so salty over getting the boot from that whack ass VH1 show. How many times are we gonna hear her bitch about why she should be “Ms. Rap Supreme?”

#11: How does Omarion feel now that he’s a “free agent?”

#12: Is anyone really checking for Cassie’s new album?

#13: Why is Ne-Yo’s new video Michael Jackson-ish? Not that there’s anything wrong with that…

#14: Why did everyone but Star Jones know Al was gay?

#15: Does Beyonce and Jay-Z know that we already know they’re married? What the hell are they hiding? The more they hide, the more we dig!

#16: Is Beyonce really gonna retire? Or is she gonna pull a Jay-Z on us?

#17: What provoked Akon to lie about being an ex-con?

#18: Who else thinks that Foxy Brown will be back in prison by 2009?

#19: Now let’s be real. When Orlando Brown went missing, did anyone ask “who?” … and after you found out it was the dude from “That’s So Raven,” you were like “ohhh, him!”

#20: Adding on to that Orlando Brown fiasco, who gave Ricky Romance the approval to manage anyone’s career?

#21: Oh, by the way. Did anyone know that Ray J released a new album like 2 or 3 weeks ago?

#1: Why did it take to long for Beyonce to get a non-singing role in a movie?

#2: Why does Weezy’s ad for condoms look suspect?

#3: Why are Reggie and Kim playing us with this fake ass relationship?

#4: Speaking of “fake ass relationships,” Chris Brown and Rihanna! Whaddup?

#5: Why didn’t Woody tell Sisqo about his call from the Lord before hitting the radio airwaves? Couldn’t he have at least put him on threeway?

#6: I’m really loving Kelly Rowland’s new “investment!” I know that’s not a question, but I don’t give a damn.

#7: But here is a question about Kelly: Why the hell does she have to name drop Beyonce, or that House of Dereon fashion line, every time she’s publicly quoted? I thought they were “solo” artists now!

#8: Why don’t Jermaine Dupri and Janet Jackson go on ahead and get married?

#9: Now that Chris Brown and Rihanna are enjoying each other’s company, publicly of course, doesn’t it seem like Beyonce and Jay-Z are slowly fading away into oblivion?

#10: Why doesn’t Cassie just accept the fact that she’s a model? Singing is not her forte and she needs to leave it alone … now.

#11: Who else is anticipating the fact that Barack Obama just might be the first African American (or biracial … whatever you want to call him) president of the United States?

#12: Does Hillary know that she’s pretty much screwed? Maybe that’s why she’s hinting at an Obama-Clinton ticket for the November elections.

#13: Something about Mario’s new promo for Dancing With the Stars looks … off. I can’t put my finger on it. What’s wrong?

#14: Does Webbie really embrace his unibrow?

#15: So Rihanna really had to tell her fans not to bring Umbrellas to the shows? Are they that stupid?

#16: Was Saaphyri serious?

#17: So Tameka really gave Usher permission release this album?

#18: Doesn’t Ashanti have an album coming out? Oops, I almost forgot!

#19: Why is T-Pain in everybody’s video?

#20: You mean to tell me Cleveland has his own spin-off, and Stewie doesn’t?

#21: Rihanna … what booty?
