Just days after Reese Witherspoon wed Jim Toth, her ex Jake Gyllenhaal was all smiles at his premiere for Source Code in Los Angeles.

Jake, who looked dashing in a grey suit, was in a friendly mood happily talking with some lucky fans and the many reporters on hand at the Arclight Cinerama Dome. Why can’t all celebs be so nice?

Flashing his signature grin, Gyllenhaal played it up for the cameras with costar Michelle Monaghan, putting his arms and hands tight around her waist. But was he able to get his flirt on at the after-party with any available ladies?

Nope, seems like the bachelor is all business right now.

At the after-party at Boulevard 3 in Hollywood, insiders tell Celebuzz Jake held court at a middle table inside and was seen talking with mostly studio types. A few other celebs in attendance at the bash aside from Jake’s Source Code costars included Mark Sanchez and Shameless star Cameron Monaghan.

“Jake was so nice, he talked to everybody who came up to him telling him congratulations,” the partygoer tells us. “He was overheard saying he was really proud of this film in particular and was excited that it was being well received so far.”

Glad Jake is in such good spirits despite Reese’s wedding!

While Witherspoon was exchanging nuptials this past weekend, Jake was spotted Saturday partying and bowling with guy friends at new hotspot Spare Room with Adam Levine.
