It's back to business for Demi Moore
and Ashton Kutcher
After talk of trouble in their marriage
emerged last week, the couple spent the weekend out of the spotlight. On Wednesday, they resurfaced – separately.
While Kutcher, 33, attended a meeting in Hollywood, Moore, 48, indulged in some pampering at a nail salon in West Hollywood.
The Two and a Half Men
star – whose partying in San Diego on Sept. 23, the weekend of his sixth wedding anniversary, led to tabloid allegations of infidelity – "looked a bit stressed and tense," says an observer. He wore his wedding ring to the afternoon meeting before returning to the Beverly Hills home he shares with Moore.
Moore, meanwhile, visited Jessica's Nail Clinic for her weekly manicure. "She was in a good mood and wore her engagement ring," says a salon client, just as X17 first reported
. "She seemed relaxed and enjoyed the pampering." She later returned home and spent time there with Kutcher.
On Thursday's Good Morning America
, a previously-taped interview aired with Moore, who was promoting her Lifetime directorial effort Five
. In that interview, Moore also revealed that she and Kutcher had exchanged gifts in honor of their new career endeavors.
To mark Kutcher's Two and a Half Men
debut, "I sent him an orchid," Moore told GMA.
Her husband, she said, reciprocated with flowers and a note that said, "I believe in you."
Of the flowers, Moore said, "It's like one of those small, little gems."
