The pair married on July 20 in a ceremony attended by friends and family including Ethel Kennedy, Rory Kennedy, and former Congressman Patrick Kennedy
Mariah Kennedy-Cuomo and Tellef Lundevall's wedding guest list wasn't short on recognizable names!
The 29-year-old daughter of Kerry Kennedy and Andrew Cuomo tied the knot with Lundevall on Saturday, July 20, in front of 400 friends and family members -- many of whom are public figures.
Mariah's father and the former New York governor, Andrew Cuomo, walked her down the aisle while her twin sister Cara, 29, and younger sister Michaela, 26, were also close at hand in her bridesmaid party.
The ceremony and reception took place on the waterfront Kennedy compound in Hyannis Port, Massachusetts, an important location for the Kennedy family's extensive history.

Among the guests at the nuptials were Mariah's aunt Rory Kennedy and Timothy Shriver, her aunt Maria Cuomo Cole and her fashion designer husband Kenneth Cole.
Former Congressmen Patrick Kennedy, Joseph P. Kennedy II and his son Joseph P. Kennedy III were also in attendance.
The wedding cake served at the reception was a sweet nod to a Kennedy family tradition. Mariah stood on a ladder to slice her wedding cake, just like Eunice Kennedy Shriver and Maria Shriver did at their weddings in 1953 and 1986, respectively.
To also honor the Kennedys, Mariah had her bachelorette party in Ireland.
Groom Tellef is Norwegian Jewish, and to honor his traditions, the couple wed beneath a chuppah that had four pillars from different locations, which represented the families coming together.
One pillar was from Ireland (for the Kennedys), another from Italy (for the Cuomos), one from Norway for Tellef's family, and one from New York as the final pillar.
It is clear that family is important to Mariah and Lundevall, who got engaged during a Cuomo family vacation to Italy over Thanksgiving weekend last year.

Lundevall had reportedly flown into Sicily as a surprise in the middle of the family trip, which Mariah's sisters Cara and Michaela and their father and were on, according to Page Six.
The couple dated for at least five years before the businessman proposed, though he got quickly acquainted with Mariah's family prior to the engagement.
He lived with his future in-laws at the governor's mansion in New York when Cuomo, who was governor of New York from 2011 until his resignation in 2021.
Former Gov. Cuomo even referred to the former Brown University football player as "the boyfriend" during some of his press briefings, and noted that the family "like the boyfriend," according to a Washington Post report.
