Lindsay Lohan joined girlfriend Sam Ronson on stage at Sam's younger brother's Bar Mitzvah to sing a duet of a Beatles song.

The Mean Girls actress, 22, and her celebrity DJ love interest, 31, belted out a version of With A Little Help From My Friends with musical accompaniment from Sam's big brother Mark Ronson on guitar, The Sun reports.

"It was amazing. Everybody loved it. Lindsay and Sam looked really loved up," said a guest at the plush Mandarin Oriental hotel bash.
