She added, "We love you so much and can't wait to kiss your little face and tiny toes. Thank you for hearing our prayers. @likemark."

The "I Am Number Four" star announced her engagement to the "Goodbye World" actor, 33, earlier in the month and tweeted her excitement. "I think I've said the word "fiancé" over 100 times in the last few hours. It sounds so nice. So happy."
