Hugh Jackman ... Ayyyyyyyyyy!

Here's a 48-year-old Hugh Jackman flashing a thumbs-up in a biker-inspired black jacket and a pair of upsetting sideburns over the weekend (left) ... and Henry Winkler posing as his iconic jukebox-punching "Happy Days" character, Arthur 'Fonzie' Fonzarelli, back in the '70s (right).

Both of these looks have jumped the shark.

We're just sayin'.

There's lots of layers to this look.

Ay papi!

Rita Ora Are You Fir Real?!

Rita Ora's fashion is something to pine after.

Here's a noble looking Rita Ora (25) leaving a club in London Tuesday night (left) ... and an abandoned Christmas tree left curbside in London after the holiday season (right).

Thy leaves are so unchanging!

Yin Yang twins? We're just sayin'.

Justin Bieber & Tilda Swinton White Hot Hair Twins We're Just Sayin'!

There's more than 30 years between them ... but Justin Bieber's newest hairdo has him looking suspiciously similar to Tilda Swinton.

Come to think of it -- has anyone ever seen the two in the same place? Could the Biebs be Tilda's greatest acting role ever?

JOHN TRAVOLTA'S NEW LOOK WILL GIVE YOU THE WILLYS

Here's the 60-year-old John Travolta showing off his freshly sprouted mane and matching chin gristle at a movie premiere earlier this week (left) and a magnetic looking makeover on the classic kids toy The Original Wooly Willy (right).

Both are attractive looks.

Leonardo DiCaprio Heeeeeere's Jack!

Leonardo DiCaprio can't handle the truth ... he's really starting to look like Jack Nicholson.

The 39-year-old actor resurfaced in Malibu with girlfriend Toni Garrn Sunday ... bearing a striking resemblance to his co-star from "The Departed."

All work and no play makes Leo a dull boy.

Tom Cruise & John Travolta Face/Off

Even Adele Dazeem couldn't tell them apart.

Reese Witherspoon Is Only Available on Netflix

Here's "Legally Blonde" lawyer Reese Witherspoon doing serious time in a safety-cone-orange outfit at a benefit in L.A. this week -- and Taylor Schilling's character Piper in her signature state issued scrubs from "Orange is the New Black."

Only one of them was actually arrested in the last year.

'Eastbound & Down' Marilyn Manson Looks Strangely Normal In TV Cameo Role

Go ahead ... take a good look.

That's Marilyn Manson -- AKA Brian Hugh Warner -- getting all actor-y on the set of the TV show, "Eastbound & Down" ... where he's shooting a cameo role this week. This is his intense look.

Manson is a huge fan of "EB&D" ... and has reportedly been lobbying the producers for the last couple of years to cast him in the show ... and it finally paid off. But he must have seriously confused the makeup people on the set ... since he arrived looking, well ... pretty dang normal.

This is the HBO comedy's 4th and final season. No word on when Manson's episode will air.

But he's ready for his closeup.

Jack Osbourne's Baby Princess Of F**king Darkness

Here's Jack Osbourne's baby daughter Pearl on the left ... and the kid's grandfather on the right.

Neither one of them can form a complete sentence.

We're just sayin' ...

Kanye West SPACEBALLIN'

Kanye West went full "Spaceballs" in Paris today ... sporting an outfit that was an obvious homage to the evil and maniacal Dark Helmet.

Let's face it ... the villain (we mean DH) has a lot in common with the rapper.

Mr. Helmet prefers to be called Lord ... Kanye goes by Yeezus -- and, of course, they both share a fondness for crushing anyone who crosses and/or talks to them.

Just sayin' ...

Anyway ... "May the Schwartz be with you."

Nanu-nanu!
