Ellen DeGeneres' first week of her 13th season was unbelievably star-studded with celebrities, colleagues, and luminaries of various sorts that Ellen genuinely seems get on with (we know it's her job, but still). Just last week Ellen welcome P!nk, whom she asked to sing the new theme song, Justin Bieber, golden girl of the year Amy Schumer, and Hillary Clinton (Ellen threw her support Hillary for the Democratic nomination).
