Whilst many fans gushed over the stunning, A-list family, many had the same thought about Liam's leading lady, who wore a stunning floor-length black Dior gown for the evening.
"I really thought that was Jen Lawrence for a sec," one commented.
"Honestly thought that was Jennifer Lawrence for a hot sec," remarked another.
"Just me or does Liam’s girlfriend look like Katniss Everdeen," pondered a third, referring to the character Jennifer Lawrence played in the Hunger Games trilogy alongside Liam.
Speaking to the Daily Telegraph, the 24-year-old revealed how she stays grounded despite being all loved-up with one of the world's hottest hunks.
"I have a great support network who continually remind me of what's important," she told the publication.
"This is incredibly grounding."

Gabriella and Liam reportedly started dating in December 2019, just four months after he and his ex-wife Miley Cyrus announced their divorce.
The couple were first spotted in public together when Liam was snapped kissing Gabriella at a beach in NSW's Byron Bay and since then, they've gone from strength to strength.
"His relationship with Gabriella is very different from Miley. They like the same things and have the same lifestyle," an insider told E! News of the couple's "low key" romance.
"It's not a rollercoaster of highs and lows. Gabriella is very laid back and even keeled."
What's more, the entire Hemsworth clan loves her.
"The family very much approves and likes having her around. They are happy for Liam that he has found someone that brings out the best in him."
