Actress Amanda Seyfried is planning her elder sister's wedding, which will take place at her farmhouse in Stone Ridge, New York.
The 29-year-old actress, who is dating Justin Long, is very excited to host her sibling's nuptials in August, reports femalefirst.co.uk.
Seyfried told the June edition of Vogue magazine: "She's with the best guy and it's going to be great - better than my own party. All the attention is going to be on her, and I'm going to slip away and enjoy myself."
Jenni, 32, added: "I never had a dream wedding in mind, but Amanda just got really excited about it and took the reins. It's very touching."
The "Les Miserables" star adores the rural home, which she bought last October, but has confessed she will think twice before taking on demanding roles regardless of the pay packet.
