Sexy Hollywood hunk Leonardo DiCaprio is reportedly going to have a new stepfather in his life. His mother Irmelin, has found love again with her school sweetheart.The Titanic star’s mom, lost touch with Klaus Teigeler in the 1950s when she moved to the United States with her parents, while he remained in their native Germany. But the pair reconnected late last year when 64-year-old Irmelin was visiting her mother in Ruhr, Germany. After their chance meeting, the couple has grown increasingly close and Teigeler, also 64, even accompanied Irmelin to Sir Elton John’s post-Oscar’s party in Los Angeles California last month. And now friends claim there is talk of a wedding. A close pal says, "He is totally nuts about her. He flew to spend Christmas with her in California and no one here (in Germany) believes he will be back." Irmelin split from DiCaprio’s father George when the actor was a year old.
