Ireland's Denis O'Sullivan leads the opening round of the Monte Carlo Invitational with a two under par 67 over the tricky Mont Agel course 3000 feet up in the spectacular mountains above Monaco.
But the former Irish amateur champion had to take second billing alongside his fellow seniors as Hollywood actors and sports stars from around the world joined them in the Celebrity-Am format new to European seniors professional golf.
Kevin Costner, star of the film "Tin Cup" is co-hosting the charity event with Crown Prince Albert of Monaco. And it was Costner, fellow actor Robert Wagner and semi-retired tennis ace Boris Becker who attracted all the attention.
Indeed a French paparazzi about 50 strong caused a few delays and rounds were taking up to five and half hours.
After a level 69 Tommy Horton said: "We're definitely second billing this week. You've got to be very patient out there. It's a tricky course. The amateurs don't know it too well and you spend a lot of time looking for golf balls. But I suppose it's the same for everyone".
Costner, star of the film "Tin Cup", partnered former US Ryder Cup player Calvin Peete, and reckoned he got it round in 82 and "had a great time being alongside the seniors who play so well."
The professionals play with a different celebrity in each of the three rounds ending Saturday.
