Kristina Orbakaite celebrated her 55th birthday in Los Angeles with her loved ones. The singer shared photos from the family celebration on Instagram.   In one of the published shots, Orbakaite poses with her eldest son Nikita Presnyakov and daughter Claudia. Presumably, the photo was taken by the artist's husband — businessman Mikhail Zemtsov. It is unknown whether the singer's younger son Deni was present at the celebration.  Recall that in 2005, Kristina Orbakaite married Mikhail Zemtsov. The couple welcomed their daughter Claudia in this marriage. From previous relationships, the singer also has two sons: 35-year-old Nikita from musician Vladimir Presnyakov and 28-year-old Deni from entrepreneur Ruslan Baisarov. Fans particularly noted the rare family photos with the children that the singer does not share often.
