Charlie Hunnam bought Jessica Chastain an ''incredibly thoughtful'' birthday present.

The 'Crimson Peak' actress previously joked she was worried she'd fall in love with the 'Sons of Anarchy' hunk on the set of the show and she's now revealed he surprised her with a lovely gift on her 38th birthday earlier this year.

She said: ''He's so nice. He bought me this incredible, thoughtful birthday present, this amazing artist and this book of photographs. He's just this normal down-to-earth [guy]. So cool.''

And while the 'Interstellar' star insists she hasn't fallen in love with the 35-year-old actor - who was replaced by Jamie Dornan when he dropped out of playing Christian Grey in 'Fifty Shades of Grey' - she does think he's ''gorgeous''.

She told E! News: ''I did not fall in love with Charlie, press out! I do love him, but I'm not in love with him.''

The flame-haired beauty - who is dating Italian fashion executive Gian Luca Passi de Preposulo - also admitted shooting the Guillermo Del Toro-directed show, which features a haunted mountaintop house, has got her interested in paranormal activity.

Speaking about her New York City apartment - which is said to be haunted by its architect and an opera singer - she added: ''I have yet to feel anything. If there [are] ghosts, let's hang out.''
