Legendary musicians Barbra Streisand and Paul McCartney are celebrating a special day - McCartney's 83rd birthday! To mark the occasion, Streisand took to Instagram to post a heartfelt message, complete with a classic Beatles reference.

"To Paul... Happy Birthday. Hope you're celebrating with a little help from your friends... including me. xo Barbra. 🌹," Streisand captioned a photo of the two posing in the recording studio.

The two music legends have teamed up for a song on Streisand's upcoming duets album, The Secret of Life Partners, Volume Two, which is set to release on June 27. The album features a cover of McCartney's 2011 song "My Valentine".

McCartney wrote about the experience of recording the song with Streisand on his website, saying "I did the session with her in LA and I was pretty terrified... But it started off with a big 40-piece orchestra on the Sony lot... and we were on 'The Barbra Streisand Scoring Stage,' so no pressure there!"

Streisand gushed about working with McCartney ahead of releasing "My Valentine" as a single in May, saying "What a joy it was to record 'My Valentine' with @paulmccartney. To share time with him in the studio was truly special!"
