Her marriage to Magnus was arranged by her maternal aunt, Malmfred, former Queen of Norway and the former stepmother of Magnus, and at the time the wife of Christina's paternal uncle Eric.
In 1133, Eric and Malmfrid fled Denmark for Norway and the protection of Magnus.
After Queen Christina, however, found out that Magnus had plans to betray them, she warned them, and Eric and Malmfrid allied themselves with Magnus' rival, Harald IV of Norway.
Christina returned to Denmark, where the only remaining information about her is that she witnessed a document by king Eric Lam a couple of years later.
