Paris Hilton may be growing up! She issued an apology — via TMZ, natch — to Lindsay Lohan for making fun of her on Hilton’s new show, The World According to Paris. In the clip for the Oxygen show, Hilton gives a homeless woman a pair of earrings, saying, “I’ll give them to you for Christmas.†The homeless woman then thanks her and mistakenly calls her “Lindsay.†Hilton laughs and then says in a voice-over, “If I were Lindsay, I’d be stealing the earrings,†Hilton said, “not giving them away.†Later on, Hilton apologized to the legally embroiled Lohan, saying, “I apologize to Lindsay for the comment that I made. I was joking around, but it was thoughtless and unnecessary.†And then, we imagine, she giggled and gave someone the side-eye. [NYDN]
