Sienna Miller donned a white sun dress to take on the heat wave in NYC hand in hand with her fiancé Tom Sturridge today. She spent another warm Summer afternoon in NYC splitting time between her loved ones yesterday. She was accompanied by her father, Edwin, and his wife to take her daughter, Marlowe, to a playground and also got in a bit more one-on-one time with Tom. The couple were recently able to sneak in a date night at the Outer Critics Circle Awards, where Tom took home the honor for outstanding featured actor in a play for his role in Orphans, which recently wrapped its stint on Broadway. Tom's not the only one in the family to be recognized for his work lately. Earlier this month, Sienna made a trip back to London to attend the 2013 BAFTA TV Awards. She didn't take home an honor, but was nominated for the leading actress award for her role in The Girl.
