Joe Biden and Jill Biden added a surprise stop on Monday while heading back to Washington, D.C.: the wedding of nephew Cuffe Owens to Real Housewives alum Meghan O'Toole King!

The president and the first lady, who had been in Delaware for the weekend, attended the "small, family wedding" at Owens' parents' home in Kennett Square, Pennsylvania, according to the White House.

The Bidens will return to D.C. on Monday afternoon.

Further details of the nuptials were not immediately available.

Owens, 42, is a Los Angeles-based attorney and the son of the president's sister and close adviser, Valerie Owens, and her husband, Jack.

The president's nephew has mostly stayed away from the spotlight since before his uncle and aunt entered the White House earlier this year.

But King, a former cast member on The Real Housewives of Orange County, is no stranger to it.

The couple went public with their relationship just weeks ago, when King, 37, posted photos of the pair together on Instagram and called Owens "my man" in the caption.

King had been dating friend Will Roos this year — as she finalized her divorce from retired baseball star Jim Edmonds two years after they separated — and was previously in a relationship with Christian Schauf.

She and Edmonds share daughter Aspen, 4½, and twin sons Hart and Hayes, both 3.

Owens and King's celebration isn't the only Biden family wedding in the works. The first lady's granddaughter Naomi Biden recently announced her engagement to Peter Neal.

When asked if Naomi and Neal's wedding would take place at the White House, the first lady said she and the president haven't been asked to host yet.
