He looked stylish at the time in a cream suit and white shirt, having just come from the Hollywood Walk of Fame.
He was there to celebrate The Devil Wears Prada duo Stanley Tucci, 65, and Emily Blunt, 43, having starred with the latter most recently in 2025’s The Smashing Machine.

The pair were honoured in a double ceremony, with Blunt’s husband John Krasinski, 46, in attendance alongside her sister Felicity, 45, who is married to Tucci.
At the ceremony, The Rock gave a speech and joked it was “about time” the pair were recognised.
Speaking about Blunt specifically, he said: “Every single day, knowing Emily, as many of us do, that is one grateful woman who will wake up feet on the ground, being grateful about every moment.
“I feel like when you’re grateful about every moment, that then leads to the thing I think we all look for, which is joy and peace of mind.
“And those are all the things I think that make up Emily and so much more.”
Matt Damon, 55, also spoke at the ceremony and hailed Tucci and Blunt, who have returned alongside Meryl Streep and Anna Hathaway for The Devil Wears Prada 2, as “legends”.
He said: “I just can’t think of two people more deserving to be added to this cultural landmark, to be giving young artists hope.
“You guys have just been doing consistently stellar work for decades, and it is such a joy to watch you guys. But beyond that, you’re two of my favourite humans that I’ve ever met on this planet.
“You’ve been able to navigate and thrive in an incredibly difficult business with such grace, and you’ve been able to navigate personally and thrive so beautifully in a very, very tricky world. We love you so much.”
