Topher Grace to wed at the weekend - report

Actor Topher Grace and his actress fiancee are to wed this weekend (29May16), according to reports.

The 37-year-old That '70s Show star and Ashley Hinshaw, 27, will exchange vows in Santa Barbara, California on Sunday, Entertainment Tonight reports.

The couple has been dating since 2014 and one of the pair's first romantic outings was in Santa Barbara in January, 2014, when Topher was photographed with his arm around his then-new girlfriend's shoulders while she clasped his hand.

He asked the Chronicle actress to be his wife at the beginning of last year (15).

Both stars are enjoying a busy 2016 - Topher's new movie, Delirium, opens later this year, while his bride-to-be's independent film, Me Estas Matando Susana, debuted in limited release in March (16).

This will be the first wedding for both stars, but Topher has been romantically linked to mum-to-be Teresa Palmer, Vanessa Lachey, Emmy Rossum, Kate Cassidy, and Minka Kelly in the past.

Family and friends like Jaime King, Laura Prepon, Ashton Kutcher and Mila Kunis are expected to descend on Santa Barbara this weekend for the nuptials.

Meanwhile, last year (15) Topher revealed another person almost came between himself and his wife-to-be - Robert Redford.

The actor told AOL his then-girlfriend started to get a little jealous about her man's feelings for someone else while Grace was filming Truth with his idol.

"I was sitting at dinner at him and I remember calling my fiance," he recalled. "We weren't engaged at the time, and the way I was talking about our dinner, she was like, 'Do I need to fly out there? Are you going to have an on-set romance?' I was so enamoured."
