Then there are those happy few stars who don't have to face this problem. Because their cousins are famous, too.
In honor of Cousins Day – July 24, to be exact – here are several celebrity cousins who don't have to worry about being the only famous person at their family reunion.
Jenny McCarthy and Melissa McCarthy

Now that both McCarthy girls have cemented their places in Hollywood, she's spoken out against criticism of Melissa on multiple occasions.

Mapother has acted in five films with Cruise – Born on the Fourth of July, Magnolia, Mission: Impossible II, Vanilla Sky and Minority Report – but to us, he'll always be Ethan, the duplicitous member of the Others from Lost.

Decades later, the second generation of Coppola cousins has gotten mixed up in the family business: Frances's daughter Sofia and Talia's son Jason have each followed in their parents' footsteps, while their cousin Nicolas (son of the comparatively unknown August Coppola) took a new name from one of his favorite superheroes and became the Internet's One True God.
Other Coppola cousins in the entertainment industry include Sofia's older brother Roman, who co-wrote The Darjeeling Limited and Moonrise Kingdom, and Jason's younger brother Robert, lead singer of the band Rooney.

As a 2000 New York Observer profile observed, when asked about Gwyneth, "a wary look crossed Ms. Moennig's eyes and her facial muscles seemed to freeze up."
Later, she revealed a certain gratefulness for their lack of resemblance: "We're totally different people. We look very different, too … No one's judging me solely on the fact that I am her cousin."

Although perhaps that would have made it weird for them to collaborate on a love song, as they did on Snoop's "Special."

When you realize that your whole perspective was whack, it makes more sense that he's cousins with Clueless's Stacey Dash.
Melissa Gorga and Ralph Macchio

Melissa Gorga was just a child when her cousin Ralph Macchio shot to fame in The Karate Kid – years later, he was working as a guest actor on shows like Psych and How I Met Your Mother when an all-grown-up Gorga became a cast member on The Real Housewives of New Jersey.
K-Ci & JoJo and Fantasia Barrino

The trio haven't officially recorded together, but K-Ci did show up at a Fantasia concert to duet on "Nobody Greater" with his younger cuz.

The difference? You have probably met most of your first cousins once removed, at least once or twice (unless your parents hated their cousins). You probably haven't met many of your second cousins once removed.
Queen Elizabeth and Prince Philip

Take, for example, Queen Elizabeth II and her husband Prince Philip, who are distant cousins.
That actually understates the complexity of their bloodlines, as Elizabeth and Philip are, in fact, related to each other twice.
Not only are the couple each great-great-grandchildren of Queen Victoria, making them third cousins, they also share an ancestor in Christian IX of Denmark, who was Phillip's great-grandfather and Elizabeth's great-great-grandfather, thus making them second cousins once removed. (Like Brooke Shields and Glenn Close!)
Like we said, royals are different.
Franklin Delano Roosevelt and Eleanor Roosevelt

Yes, Eleanor Roosevelt may have only been FDR's fifth cousin once removed, and yes, she may have been more closely related to the other Roosevelt president (she was Teddy's niece), but still – her maiden name was Roosevelt!
You could say the future president was just following in the family tradition, though; his own parents were sixth cousins.
