Last week's HBO Max documentary reunited the original cast with famous fans to look back on some of the most memorable moments from the sitcom – and one segment put Lisa Kudrow in the hot seat when she performed Phoebe's classic song 'Smelly Cat' with help from singing legend, Lady Gaga.
Lisa chatted about that jaw-dropping collaboration during an appearance on The Ellen Show on Friday (June 4), where she admitted she was quite rusty on the guitar leading into filming.
The 57-year-old actress told the daytime TV show host that she had to relearn how to play the iconic tune, but luckily she was able to do so quite easily, as she found the chords online. Check out the interview below.
