The pair wed in Italy last Friday ( and Ben thinks his ‘Runner, Runner’ co-star Justin and Jessica, who is close pals with his wife Jennifer Garner, make a great couple.

He told E! News: “I'm very excited for him. He's a terrific guy. He's a really good actor. There's nothing that guy can't do.

"Jess is great. I'm happy for them."

Meanwhile, Justin’s former NSync bandmates Lance Bass, JC Chasez, Chris Kirkpatrick and Joey Fatone are said to be furious they were left off the guestlist.

 A source told the New York Post’s Page Six: “The band were not invited and are pretty upset about it. But the wedding guests were mainly close family and friends.”

Last Thursday, the bride and groom - who briefly split last year - hosted a party for guests, were they dined on fresh-made cheese, local olives and wine, while sitting around open fires.

The night before, the group celebrated at a beach where they watched fireworks and listened to live music.

Following the nuptials, Justin and Jessica released a statement confirming their marriage and saying what a great time they had.

They said: "It's great to be married, the ceremony was beautiful and it was so special to be surrounded by our family and friends."

The 30-year-old actress initially wanted to tie the knot in an intimate ceremony in front of a few guests but her fiance has now persuaded her to turn the nuptials into a huge celebration.

A source told People magazine: "Justin and Jessica are planning a big summer wedding.

"Jessica initially wanted a smaller, more intimate wedding, but Justin from the beginning wanted a big wedding and that's what they have decided on."

Jessica has yet to decide on her dress but is "very involved" in planning the ceremony, with the source revealing the couple plan to "include all their friends".

The insider added: "Justin has promised her the best day ever."

While Jessica - who split from Justin last year only for them to rekindle their romance before the 'Social Network' star popped the question - hasn't yet found her dress, it was recently claimed she already knows who she wants to design her gown.

A source said: "Monique Lhuillier has sent over some sketches. She's Jessica's first choice."

And the pair are said to be getting a lot of help with planning their big day from Justin's mother, Lynn Harless.

The source said: "She's helping with every little thing."
