Meghan Markle's father, Thomas Markle, is reportedly having heart surgery. If that is the case, the procedure will prevent him from flying to the U.K., which means he definitely won't be walking his daughter down the aisle.Though there's no official confirmation from Kensington Palace about Thomas' current health or wedding attendance status, he told TMZ that he will go into surgery tomorrow morning. It was previously reported that he had a heart attack last week but checked himself out of the hospital so that he could be there for Meghan's big day. However, as of Tuesday, he was still having chest pains caused by emotional stress, and so he returned to the hospital."They will go in and clear blockage, repair damage and put a stent where it is needed," he said.
