Kristen Wiig is rumoured to be dating Scott Speedman.

The 'Bridesmaids' star, who split from The Strokes rocker Fabrizio Moretti last year after 18-months together, and the former 'Felicity' actor have reportedly been ''hooking up lately.''

The 41-year-old actress was spotted holding hands with the 39-year-old actor at an after-party for the comedy 'St Vincent' at the Toronto International Film Festival earlier this month.

A source told InTouch Weekly magazine: ''They spent the entire night laughing and talking.

''She's totally into Scott!''

The duo also left the event together, but another source told E! News they are just friends.

The insider insisted: ''[They] have been friends for a long time.''

'October Gale' hunk Scott previously dated his 'The Last Resort' co-star Camille De Pazzis, but split from her earlier this year.

He was also linked to his former co-star Keri Russell in the past.

'Saturday Night Live' star Kristen, who was previously married to actor Hayes Hargrove between 2005 and 2009, sparked rumours she had reunited with Fabrizio last November when they were spotted cosying up to one another at a New York Knicks basketball game, after splitting in July 2013.

She previously gushed about the musician in 2012, saying he had brightened up her life.

She said at the time: ''I will say that I'm happier than I've ever been, and I feel very lucky.''

Pressed about the source of happiness, Kristen added: 'Where I am now. Who he is. Those are the two big ones.''
