It's been a busy spell for Chris. First, his 'conciously uncoupling' status got upgraded to 'officially divorcing' after Gwynnie filed papers, and now he's apparently getting pursued by Agent Scully. Doesn't he have the life. 

According to one of The Sun's many sources: "They’re an unlikely combination but there’s definitely chemistry between them... Chris has always been keen to keep his personal life private so, as expected, the blossoming romance is very low-key... His pals are intrigued to see if it turns into a bigger deal."

I wouldn't say they're an unlikely combo - she's an older lady (46) in the acting profession. If anything, the combo of him and Jennifer Lawrence was "unlikely".
