90210 actress Shenae Grimes only wed husband Josh Beech in May, but she already knows what it takes to make her Hollywood marriage last.

During BeautyCon at Siren Studios this past weekend, the 90210 star was overheard telling guests about the solid nuptial advice she got from her mom.

“Shenae said her mom told her that sacrificing [for] and supporting your spouse is the key to a happy marriage,” one guest tells Wetpaint Entertainment. “Shenae added that being a wife is an exciting new role she’s still adjusting to.”

The happy couple showed off their marital bliss by co-DJing a set together, then sharing kisses and snuggles throughout the day.

Another adorable duo to hit BeautyCon? Kelly Osbourne and fiancé Matthew Mosshart, who looked equally smitten with each other the entire time.

What a romantic event — wish we had been there!
