Actress Jessica Biel made a great hostess and girlfriend at her dinner party for Tod’s at the Chateau Marmont. Biel and rumored boyfriend Justin Timberlake showed affection toward each other without overdoing it, and an onlooker told People that the two were “very sweet” together.

What are some ways to show affection without being obvious about it?

Cupid’s Advice:

Showing too much PDA is almost never appropriate. Cupid has some advice on how to keep things classy:

1. Hand holding: Taking each other by the hand in public is a subtle way of showing others that you’re together.

2. Little kisses: Locking lips in public can appear tacky, but a kiss on the cheek or the forehead is a cute way to display your affection. If you really can’t refrain, keep your kisses to a short peck on the lips.

3. Affectionate invasion of space: Flirting at an intimate distance can be a fun way to tease your partner, and others will  enjoy seeing love in the air.
