If you're a 'Curb Your Enthusiasm' fan who is up to date with the new (and final) series, you'll already have seen Bruce Springsteen's cameo.
In the second episode of the series, The Boss appeared in a news report on MSNBC supporting Larry, after he is arrested in Atlanta for violating a voting law.
In the latest episode that aired in the US on Sunday night, however, he made a much longer cameo that saw him share a scene with Larry, Jeff and Susie after he asks to meet Larry while passing through Los Angeles .
They meet at Jeff and Susie's house, where he shares stories about trying to avoid Don Henley from The Eagles, and where he gets his water glass mixed up with Larry's - leading to disastrous consequences for his 'farewell' tour.
It turns out that he's actually a pretty decent actor - so if he decides to make an appearance in that forthcoming biopic based on the making of his album 'Nebraska', no doubt he'll kill it.
