Elsa and Martha Go Topless, Leo and the Pope Have a Pow-Wow, and Much, Much More

Here's what all the fuss is about:

• The other day on Instagram, Victoria's Secret posted a topless photo of Elsa Hosk and Martha Hunt doing graffiti during a shoot (above). And although we appreciate the pic, we strongly disapprove of the girls' choice to forego facemasks. Safety precautions — unlike shirts and pants — should never be thrown to the wind.

• Earlier this week, actress and Fabletics co-founder Kate Hudson modeled her company's new line of Valentine's Day loungewear on Instagram (below). In related news, only people with bodies like Kate Hudson would consider that stuff "loungewear."

• Speaking of folks with fabulous physiques, we recently reached out to yoga expert Dempsey Marks for help toning up our most stubborn areas — namely, our inner thighs and butt. Watch the video below to learn her tricks, then change into your movement-friendly "loungewear" and follow along at home:

• NBC has revealed the celebrity contestants who will be competing for Arnold Schwarzenegger's approval on this year's season of "The Apprentice." They include Jon Lovitz, Boy George, Snooki, and around a dozen other hopefuls whom Arnold will eventually fire for being flabby losers and pitiful girlymen.

• 20th Century Fox and DreamWorks have debuted the first trailer for "Trolls," an upcoming animated film based on the neon-haired dolls you collected in the early '90s. Judging by the clip (below), the movie aims to explain the fantastical lore behind the colorful critters, which, for some reason, involves a moderate amount of twerking:

• Paul Kantner, a founding member of the psychedelic rock group Jefferson Airplane, passed away on Thursday of organ failure and septic shock following a heart attack earlier this week. He was 74, and even though this sucks, at least Kanter made it to his 70s, which is more than can be said for a lot of his contemporaries in the business. What the heck is going on?!?

• And finally, according to English actor Dominic Monaghan, the late David Bowie auditioned for a prominent role in "The Lord of the Rings." However, the filmmakers ultimately rejected Bowie, forever depriving fans of the sweet song-and-dance sequence that their fantasy film so desperately lacked:
