One is a millionaire model, while the other is the daughter of rock royalty.

Yet last night, legendary supermodel Kate Moss and rock royalty daughter Kelly Osbourne became London's ultimate 3am party girls as they paired up for a wild night out across the city, leaving both visibly exhausted after celebrations stretched into the early hours of the morning.

A dishevelled-looking Kate leaned heavily on her boyfriend, musician Jamie Hince, as she and a clearly fatigued Kelly exited club Punk in Soho late last night.

The 34-year-old supermodel, and mother to 5-year-old daughter Lila Grace, exited the venue unsteadily with her head down, dressed in black shorts, a sleek leather jacket, and opaque tights that bore noticeable marks from the evening's festivities, proving even global style icons aren't immune to a wild night out.

Meanwhile, a dramatically pale Kelly—daughter of legendary rocker Ozzy Osbourne and TV judge Sharon Osbourne—required the physical support of two friends as she navigated her way out of the club to a waiting car.

It appears Kate's rumored health-conscious lifestyle may have encountered a temporary setback. Recent reports suggested the model had embarked on a balanced nutrition regime in hopes of boosting her fertility.

However, judging by the night's events, making a complete lifestyle transition might require a bit more time for the famous model.

Despite both women appearing in urgent need of rest, Kate and her partner Jamie Hince, guitarist for the band The Kills, headed over to Kelly's north London flat, continuing their late-night festivities until 4:00 AM.

What exact milestone they were celebrating remained a mystery, but it was already an event-filled evening for Kelly, who had spent the earlier hours attending the annual NME Awards. Discover more entertainment updates across our platform.

Mirroring her mother Sharon's recent headlines at the Brit Awards, Kelly found herself at the center of controversy after unleashing a fiery exchange directed at event presenter James Corden.

The 23-year-old was reportedly enjoying drinks throughout the ceremony while sharing a front-row table with close friend Kimberly Stewart.

When Corden introduced her on stage as "the queen of hanging with the bands," Kelly stunned attendees by sharply retorting with a profane remark back at the host.

She also expressed frustration towards reporters on the red carpet who pressed her with questions regarding her close friend, music icon Amy Winehouse.

Kelly was particularly defensive regarding Amy's nomination for Villain of the Year at the awards show, stating firmly: "I think it's unfair to knock someone when they're down."
