Recently, we all discussed that Rooney Mara ONLY smiles on the red carpet when she is with her sister and lo and behold! Here they are again, looking very relaxed together. Remember how Keith Urban and Nicole Kidman often felt like one another’s Red Carpet Emotional Support Person? This is version 2.0, and ideally one for life. It’s very sweet to see — and extremely kind of Rooney to give Kate so much sisterly support rather than the appropriate sibling razing over the fact that she went out in only her underpinnings.
