London, February 24 : Oscar-winner Sean Penn took a dig at his former wife Madonna when the two crossed paths at an after-show party.

The 48-year-old, who won the Best Actor gong for his performance in ''Milk'', was congratulated by the Queen of Pop, who went public with her 22-year-old lover Jesus Luz at the bash after splitting with Guy Ritchie in January.

The Sun reports, gesturing towards Luz, Penn said: "Thanks. Another kid already?"

Madonna was also spotted with her Brazilian ''toyboy'' at the pre-Oscars party, also attended by Sir Elton John, Sienna Miller and Josh Hartnett.

"She was all over him at the Grey Goose pre-Oscars party at Cecconi''s in Los Angeles," the Daily Star quoted a source as saying.

"She was kissing his face off. Then she decided to invite him to join her at the actual bash - their first public outing together," the source added. (ANI)
