Tiger Woods, Wife Welcome a Son!

Tiger Woods welcomed his second child, a son, on Sunday.

"Elin and I are thrilled to announce the birth of our son, Charlie Axel Woods," the golfer, 33, wrote on his Web site. "Both Charlie and Elin are doing great...Sam is very excited to be a big sister and we feel truly blessed to have such a wonderful family."

Woods was due to compete at Torrey Pines in the final round of the Buick, which he's won six times -- but said last week that he'd skip the competition -- the first time he's missed it in 11 years -- if his wife went into labor.

Can you guess which stars these bumps belong to?

Woods and Elin Nordegren are already parents to daughter Sam Alexis, who was born on June 19, 2007 -- the day after he came in second at the U.S. Open.
