Angelina Jolie had lunch – sans Brad Pitt or their children – at Public at the Hollywood Roosevelt Hotel on Tuesday afternoon.

While the actress recently spoke about her "very grounded home," she "beamed" as she joined four women and one man at a corner booth near the bar for a mid-day meal.

The actress-turned-director looked "stunning in a long black fitted coat, a Louis Vuitton tote and her hair down," an onlooker tells PEOPLE. "She looked breathtaking with no makeup on."

As the group enjoyed a "carefree" lunch, Jolie was smiling and "seemed really comfortable and totally peaceful. Just having a nice lunch," the source adds.

Miley Cyrus made a return to one of her favorite spots, Beacher's Madhouse at the Hollywood Roosevelt Hotel, with a group of friends on Wednesday.

The starlet arrived around 11:30 p.m., wearing distressed high-waisted jeans and a crop top, and grabbed her usual front-row table. Even though fiancé Liam Hemsworth wasn't with her (he's currently away filming the next installment of The Hunger Games), Cyrus managed to have fun, smiling and laughing with her pals and hitting the dance floor for songs like "Don't You (Forget About Me)" and "Nuthin' but a 'G' Thang."

When she wasn't dancing, Cyrus was enjoying the action on stage, which included a man in a bubble and a performance by a mini Nicki Minaj. She eventually closed down the hotspot with her pals.

Joe Jonas was ready to party on Thursday night – but only with his boys.

The musician came through Beacher's Madhouse at the Hollywood Roosevelt Hotel with a large entourage at around 11:45 p.m. Once inside, the group was escorted to a table and helped by a cocktail waitress, who poured Jonas several vodka drinks throughout the night.

"He was very friendly with the staff at the club who came to say hello," an onlooker tells PEOPLE. "Throughout the night, he was approached by different women. Sometimes he was polite and other times he seemed more annoyed."

Why? The onlooker explains: "The girls were fairly aggressive with him. It was clear Joe wasn't interested in any of them."

You just can't keep Miley Cyrus away from Beecher's Madhouse!

The singer and her Hunger Games beau Liam Hemsworth returned to the raunchy show in the Hollywood Roosevelt Hotel yet again, this time arriving hand-in-hand in matching black attire.

Hemsworth wore a black baseball cap and a black T-shirt and jeans, while Cyrus was clad in cut-offs with a leopard belt, a low-cut shirt and her hair pulled back.

The longtime lovebirds sat at Cyrus's usual table in the front row, where pal Ryan Rottman joined them.

"Miley seemed in good spirits while standing at the top of a banquette for most of the night, but the couple's PDA was kept to a minimum aside from their initial handholding," an onlooker tells PEOPLE, adding that the duo stayed until the club closed.

Miley Cyrus made a fashionably late entrance to Beacher's Madhouse at the Roosevelt Hotel in Hollywood at 1 a.m. Sunday morning, showing off her new haircut and wearing high-waist jeans and a black crop top. The singer made a beeline for pal Kelly Osbourne and grabbed her to dance along to hits like "Without You" and "Superbass" while snapping pics. A few minutes later, Cyrus's boyfriend, Liam Hemsworth, arrived, and after exchanging a kiss, the couple decided to call it a night, heading out with Osbourne in tow.

Newly single Demi Lovato popped by Beacher's Madhouse at The Roosevelt Hotel in Hollywood Wednesday, grabbing a seat with pals Kim and Khloé Kardashian. The starlet was really into the stage shows, and sang along with the house auto-tune band, Pop Shop, as they played Nicki Minaj's hit "Superbass." The singer didn't seem to mind when ex Wilmer Valderrama arrived at the club, and looked on as the Kardashian sisters hit the stage when the DJ blasted the latest Jay-Z and Kanye West hits.

Looking for love – or just a friend? While out at Beacher's Madhouse at the Roosevelt Hotel in Hollywood Saturday, Lauren Conrad was "very flirty" with Glee's Cory Monteith – and at one point, appeared to give the actor her number. When she wasn't chatting up the cute Canuck, Conrad, clad in a black tank top, skirt, blazer and Chanel bag, danced in her seat, chatted with friends and sipped on a cocktail. Later in the evening, her former maybe-flame Derek Hough came by, and the two hugged and had a friendly conversation before parting ways. The star finished the night with champagne, and stayed until the club closed.
