McLaren got off to a poor start at the Monaco Grand Prix with Fernando Alonso given a five-second penalty for nudging Nico Hulkenberg's Force India into the barriers.

It has been a terrible season for McLaren so far, with no points from the first five races, and this latest incident came at the Mirabeau turn as Alonso tried to make his way through heavy traffic.

Hulkenberg was able to continue after taking a pit stop to change his front wing, and Alonso will have to serve the time penalty when he enters the pits.

Meanwhile, the race ended early for Venezuelan driver Pastor Maldonado as the brakes failed on his Lotus.

Formula One leader Lewis Hamilton made a clean start from pole position at the Monaco Grand Prix, holding off Mercedes teammate Nico Rosberg.

It's a relief for Hamilton, who was starting from pole for the first time in Monaco and was coming off a poor start at the Spanish GP two weeks ago.

Rosberg, meanwhile, held his spot well under pressure from Ferrari driver Sebastian Vettel, who started from third on the grid and tried to squeeze past him.

Sparks flew behind them as the two Red Bulls of Daniel Ricciardo and Daniil Kvyat jostled aggressively for position.

There's a simple reason why Lewis Hamilton is the favorite for this year's Monaco Grand Prix, aside from the fact that he's the F1 championship leader: he's in pole position.

The tight, sinewy nature of Monaco's 3.34-kilometer (2.07-mile) street circuit makes it extremely difficult to overtake, and the past six winners and nine of the past 10 have won from pole.

That means Hamilton has a good chance to earn his fourth win of the season and extend his 20-point lead over Mercedes teammate Nico Rosberg.

Rosberg closed the gap somewhat at the Spanish GP two weeks ago, when he ended a run of just one win in 15 races.

But the momentum is still very much with Hamilton, who recently signed a new three-year deal with Mercedes.

His remarkable consistency has seen him reach the podium in 21 of the past 24 races since the beginning of last season, with 14 wins, five second-place finishes and two third places.

With the Cannes Film Festival a short drive away, celebrity spotting has always been easy at the Monaco Grand Prix.

In the 1960s, it was film stars like Swedish actress Britt Ekland and British actor Peter Sellers who turned up. In more recent years, Brad Pitt, George Clooney, Jennifer Lawrence and Leonardo DiCaprio have all attended the glamorous event.

This year, Michael Fassbender was spotted shortly before Sunday's race, while Real Madrid's soccer star Cristiano Ronaldo turned up with British fashion model Cara Delevingne.

While Ronaldo chatted with Formula One driver Fernando Alonso — who is a huge soccer fan — in the pit lane, Delevingne sat on a McLaren car wheel.

Liam Payne of pop band One Direction was also seen strolling around the paddock area, and former world ski champion Maria Hoefl-Riesch of Germany also attended.

Glitz and glamour are part of any Formula One race, but never more so than at the Monaco Grand Prix, its showcase event where movie stars bump shoulders with royalty and sports celebrities — and hopefully take in some top-class racing as well.

As always, fans have flocked to the picturesque principality to soak up the atmosphere at the most unique event in F1, a street-circuit race which sees drivers go past the Monte Carlo casino, famous boutiques and some of the most expensive real estate in the world.

Raucous crowds gather around the glittering harbor, while others prefer to seek a good vantage point in the surrounding hills perched just underneath Prince Albert's huge palace.

More privileged spectators have a free view while drinking champagne on their luxury yachts.

In this rich playground, it's a case of the haves and the have yachts.
