John Mulaney is returning to the "Saturday Night Live" stage after a slew of major life changes happened since his last time hosting the popular sketch show. 

On Sunday, the stand-up comedian and former "SNL" writer revealed on social media that he will headline the show on Feb. 26 alongside musical guest, LCD Soundsystem. 

The comedian captioned the announcement "And just like that…" which was seemingly a reference to the "Sex and the City" spinoff that’s currently airing on HBO Max.

After serving as a writer on the show from 2008 to 2012, where he created memorable characters such as Bill Hader’s Stefon, Mulaney stepped away and focused on what became his immensely successful stand-up career. He hosted the show for the first time in April 2018 and then again in March 2019. Right before the coronavirus pandemic shut down the show briefly, Mulaney hosted in February 2020 and then again in October.
