Matthew McConaughey's Birthday Buddy: Levi!

With baby Vida in mom Camila Alves's care, Levi and Matthew McConaughey spend some daddy and me time while the family vacations in New York on June 16. "He and I have our own jokes that he and his mother don't have," the actor told Good Morning America. "He's really started to take a liking to [me]."

Go team! The father-son pair unite to root for mom's home team, Brazil, as they celebrate the World Cup in New York on June 15. He's "starting to get fun," McConaughey told Jay Leno last year.

The boys hit the ground rolling on May 22 in Malibu. The actor – and exercise buff – told Parade he wanted to get Levi "out into the world" – and true to McConaughey's word, his 2-year-old is "outdoors as much as he is indoors."

McConaughey and his mini-me, Levi, ponder the great outdoors in Malibu on March 24. "You can watch Levi, and everything he sees is for the first time, so you see the wonder in something we see every day," the actor told PEOPLE.

A cheery Levi enjoys a ride courtesy of dad in New York on March 10. "You'll do anything to get a smile from him," McConaughey shared with Parade. "I get a kick out of making him laugh."

Considering McConaughey loves hitting the beach, it's no surprise he's been bringing Levi – seen here on Oct. 22, 2009 – to the Malibu shores since he was an infant.

McConaughey, Alves and Levi get ready to ride some waves in Malibu on Aug. 30, 2009. "My son loves the shower," the actor told Fox News. "We've been to the beach a few times, but he's already spent a good nine months in 'the water' so he's comfortable."

The nature-loving duo buddy up for a moment of quiet, watching the sun set in Malibu on June 12, 2009.

Baby steps! The doting dad guides Levi on May 13, 2009, as he experiments in the surf. "There's a responsibility that comes with fatherhood that I've always looked forward to," he told Entertainment Tonight. "There's a different way of walking around the world."

Care for a bite? Levi and McConaughey share a sweet, all-natural treat during a Malibu outing on March 30, 2009. ”I'm doing everything that I was

doing before," the actor told Good Morning America, "but with my son, it has really just become a ball."
