, sharing a quiet night with Joel Madden
at West Hollywood's Chateau Marmont. The new parents looked relaxed, talking and hanging out in the lobby. Richie wore her hair down, and sported a black motorcycle jacket during their evening out.
and Marc Anthony
, walking into Madonna
's L.A. concert at Dodger Stadium like they were royalty. Lopez, dressed in all white, clutched Anthony's hand as they emerged from the backstage area onto the field. Lopez was absolutely glowing and smiled ear to ear as they waved and walked through the crowd to their seats. Meanwhile, Rachel Zoe
and husband Rodger
were seated next to Hayden Panettiere
at the show, just a few rows away from the stage. Rodger completely doted on his stylist wife the entire time, even braving the crowd to grab margaritas before Madonna hit the stage.
and Penn Badgley
, holding hands at an opulent opening party for Juicy Couture's 5th Avenue flagship store in Manhattan. But that was the extent of the PDA for the Gossip Girl
stars, who spent their time mingling with friends – including costar Jessica Szohr
– and fans alike. At the bash, waiters made rounds with caviar canapes and mini hamburgers, while a church choir performed classic-rock hits and tutu-clad ballerinas danced in the windows.
They're back! After a hiatus of a few weeks Lauren Conrad
and boyfriend Kyle Howard
returned to their favorite spot,
Teddy's inside the Hollywood Roosevelt Hotel
, for jazz night. The pair made a beeline for the bar, and
Conrad sipped a Red Bull while chatting with her female friends. Howard
stood nearby, talking with his guy pals, but the two were never far apart.
Soon, though, the couple moved to a corner near the bar – and Conrad
was all over her beau, draping herself on him.
, celebrating her younger brother Barron
's birthday at Les Deux in West Hollywood with beau David Katzenberg
by her side. The two settled into a table in the outdoor lounge, and played it low-key. Hilton let her brother – and sister Paris
, who arrived with a camera crew – be the center of attention. Later, the sisters wished Barron a happy birthday with a red velvet cake.
Ever the gentleman, Nick Zano
displayed perfect manners
when he took girlfriend Haylie Duff
to BLT in West Hollywood. Says
a fellow diner: "Haylie cracked a smile when Nick rushed a few steps forward
to open the door for her."
, feeding girlfriend Holly Madison
strawberries during a visit to Tryst nightclub inside the Wynn Las Vegas.
The pair also shared
playful hugs and kisses – and definitely attracted the crowd's
attention. The pair also visited Koi Las Vegas for a late-night meal. "They were kissing and sitting very close together looking very much like they were in love," says a source. "They held hands and stayed close."
Taking a break from filming Middle Men
in Scottsdale, Ariz., Luke Wilson
