Kylian Mbappe was in attendance as Gareth Bale's new club Los Angeles FC pulled further clear in America's top division.
LAFC, who lead the MLS Western Conference, signed Welsh wizard Bale on a one-year deal on a free transfer in a shock move for the former Real Madrid star
And the Paris Saint-Germain forward added to the star appeal in California by attending their match on Sunday night.
Not the only star in town! PSG forward Kylian Mbappe watches on as Gareth Bale's new side Los Angeles FC extend their lead at the top of the MLS Western Conference with a 2-0 win against New York Red Bulls
The MLS Twitter account posted: '‘sup @KMbappe. Taking in #LAFC x #RBNY at the Banc.'
Bale, 32, spent nine seasons with the Spanish giants after joining for a then-world-record fee of £85million but his time there petered out amid fan frustration with his frequent injuries.
His contract with Los Blancos finally ran out this summer and he departed as a free agent.
With the 106-cap international keen to get regular game time ahead of Wales' World Cup crusade in November, several clubs were vying for his services, including Championship side Cardiff.
But the former Tottenham and Southampton star plumped for Steve Cherundolo's west-coast outfit LAFC on a 12-month contract.
Bale is not the only recognised name to be snapped up by LA this summer. Former Italy and Juventus centre back Giorgio Chiellini is also swapping Europe for the States' west coast after agreeing to join the club, too.
And Mbappe, who signed a massive new contract this summer at PSG to reportedly make him the highest-paid player in the world, watched on at the Banc as LAFC won 2-0 after two goals in four minutes from Cristian Arango and Diego Palacios.
The result leaves them four points clear of second-placed Real Salt Lake in the Western Conference table, with a game in hand.
Mbappe's appearance at the Banc of California Stadium was not his first high-profile appearance during his American holiday this summer.
The France international was front and centre during the NBA draft last week, appearing during the ceremony and on the red carpet in New York.
