Is Matthew Expecting a Boy?

Matthew McConaughey and Camila Alves said they were waiting for a delivery surprise, but could they have already found out the sex of their baby?

If their baby shower gifts mean anything, then a little Matthew Jr. may be on the way!

“All the gifts were wrapped in blue paper!” an onlooker tells OK! of the presents at the June 15 Malibu bash.

The 24-year-old model was spotted earlier that morning at UCLA Medical Center -- perhaps for a final check-up? The baby, which would be the first for both Matthew and Camila, is due at the end of the month.

“They are both very excited,” a pal of Matthew tells OK!. “They’re enjoying this moment!”
