And good thing too, as the newly-minted host worried (jokingly) about her place in the male-dominated late-night hour during the opening of her chat show.
"The 'Late-Night Wars' were when hosts of late-night shows were fighting with each other like in the '90s for top ratings," Philipps began. "It was really intense. They all wanted one show. And now, you know, everyone gets a show, even me!"
"Coming into this show, one of my biggest fears was reigniting the 'Late-Night Wars,'" she joked. "And since you know I'm a do-er, I decided to nip it in the bud and I went straight to the source."
Viewers were then treated to a fun segment, where the actress was greeted by late-night O.G.s with hilarious messages and unique presents. The skit first showed a behind-the-scenes clip (filmed partially on her phone) from her previous appearance on "The Late Show," where she asked host Stephen Colbert if he had any "advice" for a new host like herself.
"Oh yeah," Colbert said. "Tell your prop people that if you have a drink on set, it has to be real liquor."
Meyers popped up next in the clip to tell Philipps that the only war that exists is which host can be the nicest to the new ones. Philipps then received a surprise delivery from Meyers: a huge bouquet of beautiful flowers.
Philipps, who recently appeared on "Watch What Happens Live," shared a video of her asking Cohen if their friendship was going to be negatively impacted by her show. Cohen reassured Philipps that everything was going to be alright.
"Busy, whatever you want," Cohen said. "You can have anything from my set! You're my girl."
Another scene showed the "Freaks and Geeks" alum receive a call from "Full Frontal" host Samantha Bee, who had some special advice for a fellow female host.
"Hi Busy, welcome to the late-night club," Bee said. "I know a lot of dudes have given you a lot of advice and I just want you to let you know. It's all bullshit. So don't cry on camera."
But it was a little too late, as Philipps was already crying. "Oh no," she said through tears.
The clip then flashed to Kimmel, who had asked Philipps to come over a few days before the show's premiere. Kimmel had a welcome gift for the "Dawson's Creek" star and presented her with his "Soul Train" award for "favorite white person" (a joke of course).
TBS host Conan O'Brien didn't have a video message for Philipps, instead he sent a special gift to her set. See what the surprise was in the clip below.
