Paul Anka is revisiting some well-known Rat Pack lore, confirming a decades-old rumor about Frank Sinatra during a recent interview with Page Six.

The singer and songwriter, who spent years around Sinatra and the rest of the Rat Pack, said he saw Sinatra in the sauna during their Las Vegas hangouts and that the stories about Sinatra’s size were accurate, as reported by TMZ.

According to Anka, the group regularly spent time together in Las Vegas, where they would sometimes gather in the sauna. During those moments, Anka said he “had trouble with eye contact,” adding that Sinatra “was very well-endowed.”

Anka also told the outlet the rumor was true, saying it was “huge” before adding, “I don’t know what that does for you!”

The story echoes a long-circulated quote attributed to Sinatra’s ex-wife Ava Gardner, who allegedly once said Sinatra may have weighed only 110 pounds but that “10 pounds of [his weight] is c*ck.”

The comment has been repeated in entertainment circles for years, though its exact origin has never been fully confirmed.

Anka also said Sinatra was not the only entertainer he encountered in those sauna sessions who had a reputation for being unusually large. He claimed Milton Berle, known widely as “Mr. Television,” was even bigger than Sinatra.

Anka and Sinatra had a long professional relationship. Anka wrote “My Way,” which became one of Sinatra’s signature songs and remains one of the most recognized recordings of his career.

Their collaboration helped cement Sinatra’s late-career legacy and added to Anka’s reputation as one of the most prominent songwriters of his time.

Good Morning!

For what is a man, what has he got
If not himself, than he has naught
……
And now, as tears subside, I find it all so amusing
To think, I did all that, and may I say, not in a shy way
Oh no, oh no not me, I did it my way
-Paul Anka
