From Kevin Bacon and Kyra Sedgwick to Tom Hanks and Rita Wilson - long celebrity marriages are often celebrated for surviving so much scrutiny in the public eye.
However, one famous couple that has survived longer than both those couples is President Joe Biden and First Lady Dr. Jill Biden, who have been married for 47 years.
Now, one of the President's secrets to a long and happy marriage has been revealed by respected White House reporter Katie Rogers.
As reported by the Daily Mail, in an excerpt from Rogers' upcoming book - American Woman: The Transformation of the Modern First Lady, from Hillary Clinton to Jill Biden - President Biden is revealed to humorously attribute the longevity of their marriage to "good sex".
Rogers - a White House reporter for the New York Times - also revealed that the POTUS will often share relationship advice with his aides, "much to his wife's chagrin".
While President Biden's playful comment may raise eyebrows, it underscores the couple's enduring bond, rooted in mutual love and respect. Despite the demands of his political career, Biden has consistently prioritized his relationship with Jill, once expressing in 2006: "I'd rather be at home making love to my wife while my children are asleep."
In fact, New York Times reporter Maureen Dowd revealed that Biden once told her that his "heart still goes pitty-pat" when he lays eyes on his wife.
The Bidens' affectionate bond is evident in their public outings, where they share intimate moments and romantic gestures. In fact, they've proven that they're not shy from sharing a PDA.
A recent date night in Rehoboth Beach showcased their enduring love, as the couple enjoyed a seafood dinner followed by a theater outing. Concluding the evening with a moonlit stroll on the beach, President Biden wrapped his arm around the First Lady, epitomizing their enduring partnership.
In addition to grand gestures, the Bidens' relationship is marked by tender moments of affection, such as President Biden's sweet gesture of plucking a dandelion for his wife before boarding Marine One.
At the time, social media users responded by saying: "I am loving having a president and First Lady who like one another."
A second added: "I have the feeling that this isn't the first time he's picked wildflowers for her. Their relationship seems very sincere."
Whether you like it or not, there's no denying that these intimate displays of love resonate with a portion of the public - proving that romance certainly isn't dead in the White House.
