The agony and the ecstasy! Emmy Rossum goes wild with a series of over-the-top facial expressions as she watches nail-biting New York Knicks game

She's best-known for her starring role in US TV series, Shameless.

And Emmy Rossum was shameless in her love of basketball when attended the San Antonio Spurs vs New York Knicks game at Madison Square Garden on Tuesday.

The brunette beauty was exceptionally animated as she watched the competition from the sidelines, pulling a variety of rather over-the-top facial expressions as she saw the action take place.

Enjoying from the vantage point of front-row seats, the 28 year-old actress had emotion written all over her face as she cringed, cheered and booed her way through the event.

Wearing a fashionable outfit which consisted of an orange top, cream jacket and skinny black jeans, the actress was well-dressed - but failed to maintain her poker face. 

Instead, she was spotted jumping up and down, gurning and gritting her teeth with the tension.

In fact, at one point she could be seen pulling her hair out in frustration while the nerves of the match manifested in her raised, crossed legs. 

And she had good reason - the league-worst Knicks upset visiting San Antonio 104-100 in dramatic over-time success.

New York's Langston Galloway scored 22 points while Russian backcourt partner Alexey Shved added 21, Lou Amundson had 12 points and 17 a career-high 17 rebounds and Italy's Andrea Bargnani contributed 16 points and 10 rebounds as the Knicks improved to 14-53, still the NBA's worst mark.

The latest look came just 23 hours after she cut a lady-like figure in a green-themed St.Patrick's Day dress.

Wearing it on Live! With Kelly And Michael and SiriusXM, the Manhattanite's frock featured a v-neck, short sleeves and a fit-and-flare skirt that ended just above her knees.

She teamed it with a pale blue overcoat and nude high-heeled pumps.

The Phantom Of The Opera star styled her beautiful brunette tresses in soft waves that framed her perfectly made-up face.

And she accessorised with a black leather handbag that she slung over her shoulder.

Emmy joined Michael Strahan on the ABC morning show standing in for Kelly Ripa who is on holiday this week.

The couple welcomed celebrity guest Theo James who promoted his Insurgent, the follow up to blockbuster Divergent, which opens on Friday.

Meanwhile, Emmy was also on the promo trail during a radio interview with SiriusXM, where she talked up Showtime's Shameless.

Now in its fifth season, the dramedy sees her character Fiona marrying Gus (Steve Kazee) on the spur of the moment.

Speaking to New York Daily News about her character earlier this month, she added: 'Fiona's gone a little off the rails. I'm a little disappointed in her journey.'

Playing the head of household of the Gallagher clan, opposite William H. Macy as her alcoholic father, requires a departure from her glamorous image.

'I like her to look a little bit haggard,' she explained to the tabloid. 'She doesn't have time or interest in beauty and perfection. Her look is part of telling the story.'

During a recent Reddit AMA live chat, the Golden Globe nominee revealed that the experience has changed her perspective on beauty.

'Fiona isn't a very glamorous character, yet most fans see her as really sexy. So to play a woman on TV who doesn't wear a lot of makeup or fancy clothes, and to have that seen as a desirable woman is a really positive thing,' she said.
