Bill Clinton's ex Monica Lewinsky plants kiss on Alan Cumming at his Hollywood star ceremony

Alan Cumming’s Hollywood Walk of Fame ceremony had fans blinking in disbelief - and not just because of the star himself.

The 60-year-old Scottish actor, a five-time Emmy, two-time Tony and BAFTA winner, was joined by an unexpected guest: Monica Lewinsky, 52, famously known for her affair with President Bill Clinton, showing up as a full-on BFF.

Cumming looked effortlessly fabulous in a bright turquoise suit jacket and matching shorts, but Lewinsky nearly stole the spotlight in a bold red pantsuit, proving she still knows how to turn heads.

The pair shared a sweet on-stage kiss, and Lewinsky even delivered a heartfelt speech honoring Cumming - cementing the fact that yes, these two really are pals.

Also on hand was Succession star Brian Cox, 79, who kept the Scottish representation strong with a speech of his own before the unusual trio posed for photos on Cumming’s brand-new star.

Capping off the star-studded moment, Cumming dropped to his knees in front of the star for a hilarious candid snap with Lewinsky and Cox looking on.

The friendship between Cumming and Lewinsky runs deep -  closer than most fans realize, despite him speaking about it before.

Back in 2016 on Watch What Happens Live, he revealed just how close they really are. 

‘She is really one of the kindest, most loyal, loving, tender, funny girls I’ve ever known. I mean, I think she’s really one of my best friends,’ he said. 

‘Yeah. And she’s been at my wedding. She knows my family.’

Cumming told Andy Cohen he met Lewinsky about 16 years ago at a Marie Claire party, and they’ve been pals ever since.

He also raved about her ‘lovely’ personality to the New York Daily News while promoting his memoir Not My Father’s Son. 

‘She’s absolutely one of the most loving, fun, clever, tender people,’ he said. 

‘The fact that she’s been able to remain such an amazing person with all that horrible bile that was heaped upon her as a young woman is testament to the person she is.’

Of course, Cumming was referencing her affair with President Clinton - a scandal that made her a household name - but decades later, it’s clear that the two have forged a genuine bond beyond the headlines. 

Lewinsky herself opened up about the incident in her first-ever public address at the inaugural 30 Under 30 summit in Philadelphia in 2016. 

‘I fell in love with my boss,’ she admitted.

Meanwhile, Ana Martinez, Walk of Fame producer, said of Cumming in a statement: ‘The Hollywood Chamber of Commerce is proud to welcome actor Alan Cumming to the Hollywood Walk of Fame. 

'As we step into the new year, we’re thrilled to honour the incomparable Alan Cumming with a Walk of Fame star. Alan’s remarkable range, fearless artistry, and dedication to his craft have captivated audiences around the world. 

'His star shines as brightly as his spirit, and we’re proud to celebrate his contributions to entertainment here in Hollywood.’

'Trailblazer, creative polymath, renaissance man, maverick, master of reinvention, and beyond eclectic: Alan Cumming is all of these and more,’ Martinez added.

Cumming first made waves three decades ago with his acclaimed performance in Hamlet on the West End, later transforming into the Master of Ceremonies in Broadway’s Cabaret 25 years on.

Hollywood audiences know him best for his iconic roles: the flamboyant villain Boris in GoldenEye, the scene-stealing Sandy Frink in Romy and Michele’s High School Reunion, and the unforgettable Nightcrawler in X2: X-Men United.

Now, Cumming adds reality TV host to his résumé as the charismatic face of the US version of Traitors.
