Nicole Richie and Joel Madden enjoyed a relatively rare night out Wednesday, but baby Harlow was never far from their thoughts.

Richie – looking fit and fab in a short black dress – and the Good Charlotte frontman headed to a star-studded dinner in honor of designer Charlotte Ronson at the Hollywood Roosevelt Hotel’s Dakota Restaurant.

And the proud papa couldn’t help boasting about his three-month-old bundle of joy. “It’s been so crazy,” he told the VIP table, where fellow guests included Lindsay Lohan and her constant companion, DJ Samantha Ronson. “Man, but it’s great.”

Richie’s fuller figure was also a hot topic of conversation.

“You’re such a pretty mommy,” said one friend, party promoter Ashley Margolis. “And your boobs are way better than mine.” (The two then posed together for a picture before Richie showed off shots of Harlow on her digital camera.)
