Kristen Stewart's 'American Ultra' Premiere, Danielle Knudson's Great News, and Much, Much More

Here's what all the hubbub's about:

• Kristen Stewart arrived for the L.A. premiere of her new film "American Ultra" in a bedazzled jumpsuit featuring a hemline that was every bit as short as its neckline was plunging (above). And — as we think we can all agree — Stewart looked every bit as fantastic as "American Ultra" looks "meh."

• GUESS model Danielle Knudson was announced as one of Sports Illustrated's newest "hopefuls," meaning she's got a good chance of appearing in their 2016 Swimsuit Issue. And despite having absolutely nothing to do with that, we'd like to take credit anyhow, seeing as we recently interviewed her about a completely different but equally sexy GUESS photoshoot. We're so proud!

• Harry Connick Jr.'s daughter 19-year-old daughter Georgia was arrested on Saturday for allegedly supplying minors with alcohol during a house party at her family's Connecticut home. Her father, on the other hand, remains unjailed despite supplying untalented minors with (arguably) more detrimental tongue-lashings every week on "American Idol."

• "Dancing With the Stars" judge Julianne Hough got engaged to NHL player Brooks Laich on Tuesday, announcing the news with an adorable Instagram photo (below). And if that pic is any indication, Hough and Laich's marriage will be the finest union of dance and hockey since D.B. Sweeney and Moira Kelly were forced to become an ice dancing duo in the 1992 film "The Cutting Edge."

• In other "DTWS" news, professional dancer Karina Smirnoff is reportedly returning to the series after taking a year off to promote a book and work on a film. ABC has yet to announce if they plan to partner her with the crappiest "star" as penance, or if they're simply planning to be extra critical of her quicksteps.

• Yvonne Craig, the first woman to portray Batgirl on the original "Batman" television series, died after a battle with breast and liver cancer at her home in Pacific Palisades on Monday. She was 78.

• 20th Century Fox has released the first trailer for "Victor Frankenstein," a reimagining of the classic monster story starring James McAvoy as Dr. Frankenstein and Daniel Radcliffe as Igor (below). But unlike other adaptations, this one asks "Frankenstein" fans to suspend disbelief and overlook Igor's absense of a hump. Otherwise, it's completely medically accurate:

• In an interview with The Times of London, model and actress Cara Delevingne confirmed she's leaving the modeling aspect of her career behind because it makes her feel "hollow" and "old." Besides, she's just as good at taking as anybody else is, so why bother with all the middlemen and formalities?

• On Tuesday, Kendall and Kylie Jenner posed for side-by-side bikini selfies (below), reportedly taken between filming segments for the new season of "Keeping Up With the Kardashians" in St. Barths. So at this point, they're not so much showing off their figures as they are taunting us with the fact that, even when they're working, they're not really working.

• Robert F. Kennedy Jr. has reportedly demanded that his daughter Kyra "clean up her Instagram" of any party pictures. Perhaps he believes them to be unbecoming of a Kennedy, because if there's one thing the Kennedy clan is historically known for, it's their sensible, moderate-partying ways.

• And finally, as reported by the Associated Press, the Beatles' very first recording contract is going up for auction on September 19 in New York. The six-page document — signed in 1961 by McCartney, Lennon, Harrison and Pete Best — is expected to fetch approximately $150,000. But as was the case in 1961, Pete Best will in no way benefit from any of this.
