Jorge Lendeborg Jr. and co-star Hailee Steinfeld, who wore a Balmain minidress, had us buzzing at the Bumblee premiere in L.A.

After what she called a "rough day" in court, Cardi B shook off her drear and put on some holiday cheer for Jingle Ball 2018. The freshly Grammy-nominated rapper brought her A-game, closing the sold-out show with her hit like I Like It. Presented by Capital One, the iHeartRadio bash beckoned countless stars to Madison Square Garden.

Friends forever! Courteney Cox supported Jennifer Aniston at the premiere of Netflix's Dumplin' at the Sunset Tower in West Hollywood. Earlier this week, Jennifer visited The Ellen DeGeneres Show where the host talked about throwing her the most epic 50th birthday that included an hour episode. The actress then replied: "I love that idea! Is it greedy of me to say that then we go to your house and have an after-party?"

The Aveeno spokesperson might be celebrating her milestone birthday in February, but she did also add: "I feel fantastic!" A large part is due to her boxing workouts with Leyon Azubuike. "Seriously, Leyon is my gentle giant,'' she said. "And he calls me 'champ,' and it's not weird."

After a lavish night out with husband George in NYC, Amal Clooney spent some quality time with father-in-law Nick Clooney at the Massachusetts Conference for Women in Boston. During their onstage chat in front of 12,000 attendees, Amal shared her own experiences with sexual harassment. "In the sense of unwanted advances that were inappropriate and awkward to deal with, yes," she replied to Nick's question. "And I think at the time, I would not have felt comfortable speaking out about it because other [women in similar situations] weren’t, and so I think that’s changed now."

The mother-of-two went on to say that she feels times are changing for her 18-month-old daughter Ella. "I think the workplace is safer for my daughter and is more fair than it was," she said. "I don’t think women of her generation are going to expect that that’s just something that we have to put up with, and I think now it’s the men, or the harassers, who have something to fear and not the victim and that’s a very good change, so thank you to the women of the Me Too movement."

Ariana Grande received her Billboard Women in Music award from legend Patti LaBelle at the annual event. During her speech, the Thank you, Next singer shared how moved she was to receive the honor. “This is really special. I want to say that I find it interesting that this has been one of the best years in my career and one of like the worst years in my life," she said as she held back tears. "I’m just saying that because I feel like a lot of people would look at someone in my position right now I guess; Woman of the Year, an artist that could be at her peak, reaching her you know, whatever, and think, you know, ‘She’s really got her s–t together; she’s really on it; she has got it all." 

The No Tears Left to Cry songstress then candidly said: “I do, but as far as my personal life goes I really have no idea what the f–k I am doing. So yeah, it’s been a very conflicting one. I just want to say if you’re someone out there who has no idea what this next chapter is going to bring, you’re not alone in that.”

Hours after Cardi B announced her split from Offset, the new mom hit club E11EVEN in Miami. The Bodak Yellow singer partied with Bad Bunny and Teyana Taylor as well as got on the mic to request songs from the deejay.

Andie MacDowell, Aja Naomi King and Amber Heard were three worthy women at the L'Oréal Paris Women of Worth Gala in NYC. Amber, who has had a busy week promoting Aquaman, spoke with HOLA! USA about women she admires. One of those women, Cyber Civil Rights Initiative founder Dr. Holly Jacobs received an award at the event at The Pierre. "I love that she made something good from something bad," Amber said in Spanish. "And when life gives you a bad experience, you have two options. You can get deeper into depression or you can go high and do something positive with that pain."

How to Get Away with Murder actress Aja Naomi King also shared, "Every woman, every human being is of worth. You just have to believe that in yourself."
