Well, this would make for an awkward Christmas get-together. In a post on her MySpace blog titled Random Thoughts (how deep!), actress Lindsay Lohan reveals that she has a heretofore unknown half-sibling: “My father just let my family and [me] know, amongst other [things] that he had another child after my little sister Aliana.” Her father, Michael Lohan, denied the claim to People magazine, and says Lindsay's girlfriend, Samantha Ronson, who was recently hospitalized due to exhaustion and stress, likely wrote the post instead. Lindsay also blogged: "I think that people go through a lot in life. And the things that we go through, whatever they may be, simply just make us stronger in the long run. That is, if we actually take what it is we have learned from our mistakes and teach ourselves what NOT to do in the future."
