Jessica Simpson given diamond ring

Jessica Simpson has been given a $10,000 diamond ring.

The singer-and-actress - who recently split from her American football star boyfriend Tony Romo - was given the enormous five-carat band after attending a party with her father Joe and mother Tina.

The West Hollywood bash was held at jeweller Pascal Mouawad's home on Monday (27.07.09), and was to celebrate Russian pop star An-Ya signing to Joe's label.

A source said: "If you didn't already know Jessica just went through a break-up, you really would have no way of telling from the way she was behaving at the event. She really seemed happy."

Jessica stayed at the party for half an hour, and reportedly received several other pieces of jewellery before going to dinner at the Beverly Hills Hotel.

Jessica - who looked fit and healthy in a black dress - refused to be drawn on her recent separation, only saying she felt "fine".

Joe later added: "She's good. She's doing very good."

Later, Jessica showed her support for An-Ya on her Twitter blog, writing: "Just left my dad's new artist An-Ya's single release celebration with my family. Good luck sweetheart! You are a doll."
