Justin Timberlake and Jessica Biel are ''in a really good place'' following the birth of their son, Silas.

The couple, who welcomed first child Silas into the world four months ago, reportedly couldn't keep their hands off each other during a rare date night at Wolfgang Puck's restaurant at the Hotel Bel-Air earlier this month, where they spent $5,000 on food.

A source told US OK! magazine: ''[They're] more bonded than ever and in a really good place.

''[They] couldn't keep their hands off each other.

''They looked very much in love, and Justin was even entertaining Jessica with his beat-boxing skills during dinner.''

Another insider told Life & Style magazine: ''[Jessica] looked slim and stunning in a cream colored '50s-style skirt, matching top and strappy sandals. You could tell she was feeling sexy and confident after dropping all of the baby weight.

''They were kissing while waiting for their car in the valet area.

''At one point, Justin serenaded Jessica and they did a little dance together. They looked like two teenagers madly in love!''
