The 27-year-old Reign actress and Sam tied the knot last Saturday, May 14th in London, England in a private ceremony.
During their reception, musical group Motown Supreme performed and the group shared a sweet thank you note from the couple on Facebook.
“You guys were extraordinarily brilliant, from the first song to the last number you had everyone on their feet,” Anna and Sam wrote. “So fun, so talented and such a pleasure to work with; we are enormously grateful to you for making our wedding reception so special. Now we just need to throw more parties so we can have you play again. Thank you!!’
