ActressLindsay Lohan has a new half sibling. Her father, Michael Lohan, and his wife, Kate Major, welcomed their second child Wednesday, a boy named Logan. "Kate and I are ecstatic. A bit late for Christmas but the best gift imaginable," Lohan, 54, told Us Weekly in a statement. "What a way to bring in the new year! God has blessed me with the best children a father could ever ask for -- but I'm done!" He and Major, 32, who married in October, have another son, Landon, born in January 2013. Besides Lindsay, 28, Michael Lohan has three other children with his ex-wife, Dina Lohan, of Merrick: Michael Jr., 27, Ali, 21, and Cody, 18. In November 2012, a DNA test confirmed Lohan also is the father of then-17-year-old Ashley Horn, his daughter from a 1990s relationship with Kristi Horn.
