J.P. McManus, a horse racing billionaire, and Gregg Ontiveros, CEO of the marketing firm Group O, shared the amateur title at the Pebble Beach National Pro-Am, but with all due respect, they are hardly the types to attract a huge following.

Here's a look at 10 celebs who brought some star power to the tournament, which Phil Mickelson won in spectacular fashion:

Tony Romo

Romo, seen here on the 18th green with Mickelson, has some legit golf chops. He played in high school and has made a few attempts to qualify for the U.S. Open. Romo was paired with Tiger Woods, and they finished 17th in the pro-am.

Fergie

This was a bonus dose of celebrity flair. Fergie wasn't playing, but her husband, actor Josh Duhamel, was. Fergie popped up at the Spyglass course on the opening day of the event and fielded several autograph and photo requests.

Jim Harbaugh/Alex Smith

The 49ers coach had his quarterback serve as his caddy. Clearly this isn't an arrangement that would work with every NFL coach-QB combo.

Lucas Black

Black was the star of the golf movie "Seven Days in Utopia" along with Robert Duvall.

Aaron Rodgers

The NFL MVP has appeared on The Golf Channel's "Playing Lessons From the Pros" series.

George Lopez

This was the eighth appearance for Lopez, a Pebble Beach resident.

Bill Belichick

In an interview during the CBS coverage of the tournament, Belichick said golf was a nice escape after losing the Super Bowl: "It's a tough loss, a tough couple days, but Pebble Beach is a great spot to take your mind off some of the troubles we had."

Bill Murray

The perennial clown prince of the tournament won the pro-am portion in 2011 with partner D.A. Points.

Nick Saban

Saban was paired with pro Bud Cauley, who played his college golf at Alabama.

Matt Cain

The Giants pitcher is 2 for 2 in making the cut at Pebble.
