Were Jeremy Renner and Scarlett Johansson getting cozy on the Oscar red carpet?

The pair posed together for photographers -- although each came with different dates. (Renner, took his mom; Johansson her talent agent, Joe Machota.)

The 'Hurt Locker' star was nominated at this year's ceremony for his supporting performance in 'The Town,' while Scarlett presented best sound editing and best sound mixing at the awards with Matthew McConaughey. (Renner ended up losing to 'The Fighter' star Christian Bale in his category.)

Johansson is newly single, having split from husband Ryan Reynolds earlier this year.

So do you think these two are heating up? Or was it just a friendly Oscar hug?
