Life's a Beach for Tito & Jenna

After two weeks of arrests, fighting, restraining orders, press conferences, drug tests, hospitalizations and reconciliations, unmarried couple Tito Ortiz and Jenna Jameson enjoyed a beautiful, peaceful day in Huntington Beach this weekend with their twins ... and Jenna's twins.

Sources close to the couple tell us the two spent Mother's Day together -- and Tito even splurged on a gift ... "one of everything" from La Perla lingerie shop.

Relationships are a lot of work.
