Matthew Lowe’s wedding was a family affair for the Pratts and the Schwarzeneggers.
The elder son of Rob Lowe and Sheryl Berkoff married Emily Markus in Santa Barbara, Calif., on Oct. 10. The weekend nuptials were star-studded. The celebrity guests included Maria Shriver with her four children and their spouses: Katherine Schwarzenegger Pratt and husband Chris Pratt, Patrick Schwarzenegger and wife Abby Champion, Christina Schwarzenegger and Christopher Schwarzenegger.
Just over a week after the ceremony, Katherine, 36, shared several family photos from the wedding on Instagram, with “All You Need Is Love” by The Beatles playing in the background.
“All you need is love 💕,” she fittingly captioned the carousel posted on Monday, Oct. 19.
The song choice and caption referenced the text printed on wedding photo strips. Wedding guests appeared to have been given the option to take photos, which were then printed in black-and-white with the bottom reading line by line: “All you need is Love,” “EMILY + MATTHEW,” and “10.10.26.”

Katherine wore the “RAYE” dress from SIEDRÉS, a brown and yellow floral jacquard satin maxi dress with a halter-neck tie design and a flared two-tone skirt. Meanwhile, her mother, Shriver, 70, wore the “Donya Velvet Dress” from Reformation, and her sister, Christina, 35, wore Ramy Brook’s “Tatiana High-Neck Satin Gown” from Saks Fifth Avenue, Katherine specified on her Instagram Stories.
Katherine’s sister-in-law, Champion, 29, opted for a floral maxi dress with a corseted button-up bodice.

Shriver shares her four kids with ex-husband Arnold Schwarzenegger. Arnold is also dad to son Joseph Baena, 29, whom he publicly revealed in 2011 that he had fathered with his longtime housekeeper, Mildred Patricia Baena.
The family has been connected to the Lowes for years. Rob, 62, is a longtime friend of Arnold and Shriver, even going as far as calling them his “second family” on Jimmy Kimmel Live! in 2019. Berkoff, 65, is the godmother of Katherine, Rob told Extra in 2019. He and Chris also costarred in Parks and Recreation. Last year, Rob attended Patrick and Champion’s wedding.

Other A-listers at Matthew and Markus’ wedding included Katy Perry, Zoe Saldaña, Marco Perego-Saldaña, Cameron Diaz, Adam Levine and Behati Prinsloo, plus Gwyneth Paltrow as the officiant.
The ceremony came amid tragedy for the Lowe family, following the Sept. 29 death of Fiona Lowe, the 13-year-old daughter of Rob’s brother, Chad Lowe, and his wife, Kim Painter. Chad, 58, and Kim, 52, were in attendance for Matthew’s wedding with daughters Mabel, 17, and Nixie, 10, per Page Six.
