A source told the New York Daily News newspaper: "Penélope and Orlando
couldn't keep their hands off one another - they were making out the whole
night.
"It was crazy! Touching, kissing - even a little bit of groping. And in view
of tons of actors, too, like Leonardo DiCaprio and Ryan Gosling."
The couple also "flirted outrageously" at a pre-Oscars party at Los Angeles'
members club Soho House.
A source said: "Orlando and Penélope flirted outrageously while playing
pool. Penélope seemed more than a little smitten and afterwards they retired
to a corner for drinks - they couldn't keep their hands off each other."
The 32-year-old 'Volver' actress also helped Orlando celebrate his 30th
birthday at Los Angeles nightclub Teddy's last month, where the couple were
said to be inseparable.
A source said: "Penélope was never further than arm's length from Orlando,
even when he was surrounded by other women on the dance floor."
