"My surprise party was flawless for Michelle McCool!!! Great lunch with friends and family. Im so excited for her bundle of joy!" Guerrero wrote.
McCool is married to The Undertaker, who will face Triple H in a Hell in a Cell Match at WrestleMania XXVIII on Sunday. She stated earlier this week on Twitter that she would be on hand for the 'Mania festivities in Miami, Florida.
Despite her retired status and apparent pregnancy, the four-time champion is not ruling out a return to the ring. When asked this week on the microblogging site about the possibility of a squared circle return, she stated "time shall tell" and "never know" in two separate messages.
