New photos have surfaced of Sandra Bullock and Ryan Reynolds getting cozy in Texas taken this past September ... during the time the 34-year-old Green Lantern star was married to Scarlett Johansson.

Bullock, 46, and Reynolds have denied reports of a relationship, however the two A-listers have been hanging out together for quite awhile now on the down low. During their trip to Austin last September, Sandra took Ryan and baby Louis to visit her sister Gesine Bullock-Prado who owns the downtown bakery Walton's Fancy and Staple.

This past December, Scarlett Johansson pulled the plug on her two year marriage to Reynolds. Makes you wonder if ScarJo was aware of her then-husband's rendezvous with America's sweetheart.

Online reports surfaced earlier this week that Sandy and Ryan spent New Year's Eve together and that the two are Hollywood's hot new couple. Sucks for Scarlett, but something tells us she'll find a new hottie in no time.

A rep for Bullock says she and Reynolds are "nothing except good friends."
