That hair! Jennifer’s pre-Friends throwback snap has made our day

We've seen enough flashback episodes of Friends to know what Rachel Green looked like as a teen, but it turns out Jennifer Aniston looked almost identical to her in the early days.

Years before she got her breakout role on the NBC sitcom, Jennifer starred in another TV comedy called Molloy – with none other than The Big Bang Theory's Mayim Bialik.

Mayim took to Instagram this week to share an amazing throwback of herself aged 14 with a 21-year-old Jennifer beside her.

"Yes this is me and Jennifer Aniston in my childhood bedroom. We did a show together before I did 'Blossom.' #tbt" wrote Mayim next to the sepia-tinted snap.

Anyone else see the resemblance?

Last year Mayim shared another – and equally hilarious – early Nineties throwback, this time showing Jen rocking dark, almost black hair and a tartan miniskirt. 

Oh-so emo.

We are LOVING these blasts from the past – wonder how Jen feels about them, though?
