Demi Moore was all over Sean Friday at the opening of an art gallery on Thursday night (15.05.14).

The 51-year-old actress, who started dating the 27-year-old rocker last July, didn't walk the red carpet with her boyfriend at the opening of the De Re Gallery in Hollywood, but things heated up between them once inside.

An eyewitness told UsMagazine.com: ''She nuzzled up next to him, whispering in his ear and they were laughing together.''

The drummer played with the brunette beauty's flowing locks before they left separately and met up for dinner at a restaurant across the street.

The source said: ''He walked by her to signal he was ready to leave, and brushed his hand across her lower back.''

The duo started dating almost a year ago after her eldest daughter, Rumer Willis, introduced them.

They were first photographed together in December on holiday in Tulum, Mexico with Rumer, 25.

Demi's inner circle have high hopes for her and Sean and a source previously said: ''It's a good match. Sean is a stable, easy-going guy.''

The 'LOL' star's divorce from her third ex-husband Ashton Kutcher was finalised in November, following their split in 2011.

The 36-year-old actor is now expecting his first child with his fiancée Mila Kunis.
